Wow, that runs good! Im around 3400lbs and only 10.2cr on 94 octane pump gas with an iron head, but that is definitely encouraging..I wonder what your sons car would like at my weight and compression

Honestly I know his car is heavier than what I said as it is not gutted but hopefully we will weigh it at the Halloween Classic at Norwalk. His engine ran 10.20's in my car on 93 octain back when my car weighted 2550# last year. It almost a waste to run alcohol with 11.3 comp but he thinks its more consistent. I think its a pain in the butt compared to pump gas. I could see it if he was 13.1

Does he cruise it around town, and drive a couple of hours to the track and then back home?
This is what Matt wants to do...not sure it's a viable option when running an 8" converter and alky!!

Here's what my car did with a 500HP W2 headed 360 when I wanted it to be a street/strip car:
1.8xx 60ft using a streetable 3500stall 9 1/2 converter! Ran 11.50's at 119-120mph.
Changed the converter, and instantly ran 1.60 60ft. and 11.teens! That same combo eventually ran 10.70's...but not street friendly!!

Brian

Brian, can you see I haven't given up on the short stroke stuff yet?? LOL

Everything above is true, except I don't drive it to the track anymore as I trailer it in case of breakage...but yes, I should have mentioned driving around town ALOT, and highway use also...ah, the voice of reason lol

Stroker is something I am still debating as well- lots of good running stroker combos posted, but not many stock stroke ones...decisions decisions

I am in the same boat...shooting for 10.9's with a street-friendly smallblock

Just picked up a complete (in boxes, haha) 360/727 to build a new motor for my car...as much as I want to keep it cheap/easy...I think its going to end up a stroker, lol
DJV's recent build has inspired me

Let's hear how fast you have gone with a 3.58 stroke crank combo, and what your combo was to get there

Want to run the 10.90 index class at my local track and still keep the cast crank stock stroke 360 if I could rather than stroke it. I think my limitation will be my 3400lb weight, 4.10 gear by 28" tire, and 10.5:1 compression max (iron head pump gas street car)

I guess I can't help but ask the question- Why a 360? I know it can be done and may save you some money on using a cast crank but that's not a good place to start cost cutting for what you want to do. You need to turn more rpm with the 360 to get the same job done and if it happens to come apart you won't be money ahead.
Why make things more difficult than they need to be- put a forged 4" arm in it and don't look back.
I know, I know...not what you wanted to hear...

I hear ya...I just have more respect for a little engine getting it done then just stroking it as the solution- not to mention the wallet is kinda tight right now to move up to a 4" forged crank and forged pistons (Already have the scat i-beams in this engine).

More than likely if I keep it a stock stroke it will just get a small hit of the spray to run the number- thinking a 100 shot should do it. I was just curious to see how "on the edge" some 10sec. builds were. Brian already filled me in on what I needed to do if I wanted to stay 3.58", and I just wanted to get an idea of how others were doing it as well

A friend of mine ran those numbers w/ a stock bottom end 360, Ported magnum heads, 510 cam (I think) and 10-12lbs of boost. Nothing fancy at all. He drove the car everywhere. It was a 67 Valaint.

Re: 10 sec stock stroke 360 combos - 09/21/12 01:08 PM

I just cant see skimping on a crank and then spraying that cast crank to make up for it. You could sell your current rotating assembly and get the stroker crank and have years of fun, then maybe add spray down the road.

Im wanting to do the same thing in the next yr or 2, I want a streetable 10.90 small block, hopefully a Gen3 Hemi.

Re: 10 sec stock stroke 360 combos - 09/21/12 01:20 PM

My 360 has edelbrock heads with 2.05 valves and shady dells 5 angle valve job on them(had a broken valve forcing some changes) they are unported otherwise. Solid roller 258@.060 and .645 lift with 1.6 RRs. KB107s at zero deck for 11:1 compresion. TTI step headers and full exhaust out the stock tips. TA4500 8" converter 727 and 3.91 gears with 275/50/15 MT ET Street radials. I don't know what it wieghs, last time I wieghed it was 3550lbs with driver. The car and driver have lost some wieght so I would say 3400ish on the starting line.

Its been 11.46@116.5 and it still has plenty to be sorted out. I have been having some ignition demons that have forced a 6000RPM shift point and it "feels" like it should be shifted higher but I don't know for sure yet. I think it could have .20s or .30s in it when sorted out.

COuld it go 10s? I think it could go 10s with a new exhaust system(this one is 16 years old with muffler shop bends) ported heads, and maybe a cam change. But I have a nice .020 over 340 block and a 4" crank in the garagefor that. My goal is a full trim street car that will go 10.50s. I just did drag week and I am hooked, so 100% street friendly is a must.

EDIT, I might go to a low gear 904 over the winter. I have run one before and going back to a 727 cost me a few tenths. It had nitrous on a pig 360 back then and I had to up the shot to get the ET back but it still wouldn't 60 the same. No more broken converter snouts though!

Re: 10 sec stock stroke 360 combos - 09/21/12 04:40 PM

Boost is out of the equation for now as I already have the spray ready to go. I have the Ross for a stroked ( scat I beams) in my current motor but would have to sell used pistons ( one with some vtp contact) and a stock 360 crank that is internally balanced... Don't think I'll get much for it too be honest

In all fairness I really think 100 shot on a 450hp stock. Rank motor wouldn't be too bad, but then again I'm no expert

Re: 10 sec stock stroke 360 combos - 09/21/12 05:10 PM

I doubt a 100 shot is going to hurt your combo, although it might not be enough for 10.90.

Re: 10 sec stock stroke 360 combos - 09/21/12 06:31 PM

To be competitive in a 10.90 index class either you have to be capable of 10.70-10.80, or just 10.90 and make all perfect passes.

Its the very first set of edelbrock heads that I ported. They do have a 2.05 intake valve but I pushed for low lift numbers because of the small cam we are using. Trust me there is no magic making a small block run 10's anymore. My son gasket matched the intake but we never touched the plenum on his intake. I did tube the pushrod holes and bolt holes but I do that on all the Edelbrock heads I do. Cheap insurance so why not.

I will add that using a low gear set 904 and a 5000 stall convertor compared to a 727 and a 4000 stall convertor is a big, big difference with this combo. He hurt his convertor so we put my old 727 in his to get him out again and he slowed drastically I think mainly because of the convertor.

Yes, I am aware of that. My plan was to spray it till I hit 10.70's 10.80's, then try to come down on the tune and get it as close as possible to 10.90. My reaction times are spot on, it was my missing shifts that hurt my consistency...but that shouldn't be an issue with the automatic im putting in

thats moving real good! If only I could get my car lighter- there isn't much for me to pull off of it, so im kinda stuck where I am...If anything, it will be getting heavier when I add a cage to the car.

thats a pretty impressive combo man

Did it run 10's consistent, or mostly low 11's?

Made it to the 1/4 mile track once, ran 10.97, then broke the rear end which took out the sprag in the trans too.
Ran mostly 1/8 mile (7.0s) which would be 11.0s in the 1/4. If it had the proper 5500-6000 converter, and 4.56 gears it would likely have run 10.7s.

This combo obviously works very well and maybe a few things that we dont know about this setup or everyone would have a mid 10 secound pump gas 360. As we can see there isnt to many other posts with combos like this that run even close to this setup. Definatly works really good.

Thanks for the kind words. My main point that I am trying to get across here is its as simple as matching up the proper parts for the job. Don't use a 625 lift cam if the heads peter out at 550. Don't run a 850 holly or a dominator if it really only needs a 750. Don't shift at 6800 only to find out it runs faster at 6400. Matt's car is set up way better than my car so lets pick my combo apart.
408 engine .030 over 4" K1 crank
App 11.3 comp
ported edelbrocks stock 2.02 valve
super victor intake. (lots of porting work to get it to flow like I wanted)picked up in a trade. would never buy one as I like the victor.
4:88 gear. This car is begging for a 4:30 gear
Powerglide trans. Consistant but gives up lots of ET.
750 holley. Definiatly needs more but with the 4:88 gear rpm would be way out of its power range.
Matt's cam 520 lift mine is 550
My car is app 2800# his car app 3200#
14-32 tire (way over-tired)
My last weekends best pass
10.16@129.53
60ft 1.40
As you can see engine for engine his is an over performer and mine is an under performer but it still shows how simple the combo can be. I personally want to see MORE over performing Mopars at the track. Off subject but a friend of mine just ran a 8.88 last weekend using a stock 400 block stroker engine, Indy tunnelram, and ported EDELBROCK heads. Guessing his duster weights 2400-2500 pounds. Sounds like a nice combo to me.

They were not the newer victor heads either.

Makes me want to build a smallblock. Also makes me think my 500" big block is kind of a pooch after reading this. ported raised port heads, solid roller cam, 1050 dominator, coan 5000 converter,3700 lb b body best of 10.57. I have a bunch of used parts put together that must not work that good together.

Re: 10 sec stock stroke 360 combos - 10/26/12 02:52 AM

What you have to do is get peak power numbers out of your head. At the race weights most of us deal with- Average power is key. HP in the 500+ range "Can" get you there IF the torque curve is working for you and your chassis. Why do you suppose the 408/416 combos are so wildly popular? Its because they make a boat load of grunt and usually well below 5000 rpm.

You are on the right track with those heads and a stock stroke 360. Concentrate on torque production with most area under the curve and you will reap massive benefits. Look long and hard at your headers. J.Rob

Hey J. Rob, thanks for the input man!

What do you mean by getting peak power numbers out of the head? Im assuming that is done via cam selection?

And my headers- that is something I have been struggling with...Can't decide if I should leave my air gap dual plane and 1-5/8 headers alone, or if I should step up to the single plane and go bigger on headers. I know the former will make more torque, but im wondering if the latter will make the same amount or more of torque but also help upper rpm

Thats why im looking to see what success others have had. Im willing to gear the car and give it the converter it needs, its just compression that is the issue because it HAS to run on pump gas and it has iron heads

Re: 10 sec stock stroke 360 combos - 10/26/12 03:20 AM

Yes be careful with cam selection. It is very easy to get sucked into the bigger is better philosophy. J.Rob

Re: 10 sec stock stroke 360 combos - 10/26/12 03:37 AM

Here is what I have so far

365ci, cast crank, 10.25:1cr, SRP forged flat tops, Scat I beams (has to run on 94 pump)
RHS heads ported 290 .600lift int, 212 exh
Hughes 1.6 rockers
Air gap intake (have no problem changing it out for a single plane)
750cfm carb- I am limited to this size for the class I am running.
1-5/8 headers (wondering if I need to go up, or if I should stay as is for torque), 3" x pipe exhaust with bullets and dumps
26" ET streets or radials and 4.10's (did some calcs and going to the 26 from my 4.10's and 28's will be close to a 4.30 ratio- think I could leave it and see if it e/ts in the low 11's/high 10's?)
904 with a low gear set, converter undecided, but probably 5000+
3400lbs with me in it, caltracs

Cam so far is a solid flat tappet looking like 247/257 at .050", 586/610 lift, 108 with 3 advanced ground in (105 ICL)

Anywhere you can take weight out of the car?

Radials are faster, period. 26" tire and 4.10's will be perfect.

Not really... I weighed the backseat that I never use, and its close to 50 pounds. But then im adding more weight by having to cage it. Thinking of pulling the heater as well, though not sure how much im going to save there. Already has no ps, glass hood, aluminum wheels, installing kirkeys, going to a 904 trans to try and save weight there.

Would more gear do the trick? I am not opposed to it, but I don't want more than a 4.56 or I think it will be a little much

I don't have tires yet, so its a matter of deciding and then choosing. I hear radials are faster, but not on marginal tracks.

Also, what is that chart you posted?

Re: 10 sec stock stroke 360 combos - 10/26/12 03:51 AM

Its a gear ratio/ tire calculation. It shows speed at given RPM or RPM at a certain speed.

I input a 26" tire and 4.10's so you could see where you are at. I'd leave the 4.10's

Cool program man! So it looks like to go about 120mph I would be trapping 6800rpms (ideally). And im going to be using the 2.77 gearset too, so that should help off the line I am thinking too.

Anything in the combo you would change, other then weight? is the dual plane and smaller headers good for torque production? I have a 1" open spacer right now, could try a 2" on top of it also

Re: 10 sec stock stroke 360 combos - 10/26/12 04:03 AM

Solid roller will make more power than a flat tappet.

The rest seems pretty set. You can always swap the intake or headers later to search for more power in those area's. Not much else that can be changed easily.

Put a bigger Carb on it with the dual plane. I have found that 850 HP and 825 Mighty Demons work well. The old style 950 HP seems to work well also. We've run them with 2" spacers on many engines like yours.

***Edit****
I missed you are limited to the 750 carb. The only other thing I'd suggest is picking up a 750 off a Comp Racer maybe.

Re: 10 sec stock stroke 360 combos - 10/26/12 11:06 AM

The headers are probably holding back 20ish HP. I'd go with TTI step headers personally. Keep the AirGap you need the midrange torque. Don't go any less than 5000 on the converter. Low 11s should be very realistic.

Yea, unfortunately I am limited on the carb size which kinda sucks- even throttle blade restrictions. I have to see about getting a 750 carb that makes more power or is tweaked or something, just need to see what the final rules end up being for this class as they are still in debate right now.

You have ran 2" spacers on the air gaps and it liked it??

What about stepping up to a 1-3/4 or 1-7/8 header. I was thinking of changing headers this year from my cheapo hedmans, but TTI's I think are quite the ripoff.. Was thinking Doug's or Hooker Comp's, but im worried the bigger tubes will kill torque

Any dyno or magazine tests out there testing the TTI stepped headers??

RHS heads ported 290 .600lift int, 212 exh
Hughes 1.6 rockers
Air gap intake (have no problem changing it out for a single plane)
750cfm carb- I am limited to this size for the class I am running.
1-5/8 headers (wondering if I need to go up, or if I should stay as is for torque), 3" x pipe exhaust with bullets and dumps
26" ET streets or radials and 4.10's (did some calcs and going to the 26 from my 4.10's and 28's will be close to a 4.30 ratio- think I could leave it and see if it e/ts in the low 11's/high 10's?)
904 with a low gear set, converter undecided, but probably 5000+
3400lbs with me in it, caltracs

Cam so far is a solid flat tappet looking like 247/257 at .050", 586/610 lift, 108 with 3 advanced ground in (105 ICL)

What do you guys think, can it be done??? are low 11's in the cards at the very least?

OU812 did some testing with headers and the TTI 1 5/8"-1 3/4" step made very good power. Straight 1 5/8 will definitely hurt. 1 7/8 may be too big, but it's usually better to stay a little on the conservative side.

Your combo has good potential as I've been fast with less footbraking! High 1.40 60's, 7.0's in the 1/8 and 11.20's in the 1/4.

Stock stroke 360 with unported RHS/Indy heads, O-deck flattops with approx 63-64cc heads (about 10.5-1) .474" lift with actually a bit more duration, Holley Strip Dom. intake, 1" 4 hole tapered spacer & Holley 750. 904, 2.71 low, 5,300+ actual flash converter, 4.86 gears with 30"x9" Hoosier lightweight radial slicks ................at 3,540+ lbs! There is more in it but not quite sure if I can hit 10's if I pull out all the stops in VG air.

You gotta do some fine-tuning too - crank scraper, I think the newer all-aluminum Holley carbs work better than the old versions (but test a lot with jets, squirters and pumpcams), Amsoil synthetics throughout, the 3" x-pipe helped me a bit while using Dynomax Ultra-Flo's. I do shift around 67-68 & go through at a bit more. A dual plane might be better if you don't go with more gear, but it worked better for my combo. More gear with a taller tire will yield better, more consistent results - provides a little more rubber on the track and the extra "leverage" may help a bit.

An Autometer playback tach is a valuable tool if you can afford it. I've learned a lot from it and have seen changes in it, like converter flash, flat spots, rpm drops, etc. when tuning the carb. Optimizing 60's through carb tuning is cheap ET reduction.

As was mentioned earlier, you will need to get it at least into the 10.70's to be able to run 10.90 in bad air.

Thanks for the reply! Gives me some hope

Was Brian's testing with the heads on a stock stroke motor, or a stroker? I will have to ask him about this since I am also discussing the combo with him right now as well

That engine combo is very similar to mine- I have ported RHS heads, 64cc so 10.25:1 compression so that I can run 94 pump without issue. My car weighed 3400 with me in it with the Dana- but ditching the back seat, heater, going to monoleafs over the multis, and the switch to the 904 from the 4 speed setup I am hoping will shed some weight (but the cage will add some back

). Im hoping I can get the car down to 3300 with me in it if possible

I am currently running a kevko pan, but no scraper or windage tray. Is there a company out there that makes a good scraper? I currently have the Holley 750 street HP, and have thought about getting a different carb (I am limited to the 750) but not sure how much difference there is between the race and street versions though. I am running a 3" exhaust already with x pipe, going from Borla XR-1's to bullets- only real difference should be weight and the more hellacious sound

Unfortunately I am limited to the 26" tire for the class- I would rather keep my 28's since I feel they look better, not to mention the better foot print. All the calcs I have done are showing the 26" tire from the 28 with 4.10's would be like running a 4.30 gear with the 28's, so im hoping that will help out as well- I am willing to change if I will need a ton more for sure, but I am thinking of leaving it as is,and if after first testing I need more gear, order a set and install them.

I actually just sold my tach to a friend as funds towards purchasing a playback tach. I think that it could definitely be a help as well. For converter, I will go with whatever stall it needs, not too worried anymore about it being too big for the street.

The class right now is a high ten (10.9 at best so far) heads upclass, but if I can run 11 flat, I think I will be competitive enough to atleast have some fun. Although it is heads up, they are implementing some restrictions so the class does not get away from itself

Re: 10 sec stock stroke 360 combos - 10/26/12 05:26 PM

Im really interested mostly in whether my cam will work or not- I know the lift is fine, but im wondering if I need something with more duration?

Converter, gearing, and whether or not I need a single plane or different headers is what I am trying to figure out. I only have one test session before the class starts in May, so i would like to get the combo as close possible the first time around (I know thats hard, but thats why I look to those who have done it for some advice and knowledge)

Re: 10 sec stock stroke 360 combos - 10/26/12 06:30 PM

Rules have been finalized- carburetor spacer can only be a max of 1.20" tall and carburetor throttle blades are limited to a max of 1.800" in size.

Re: 10 sec stock stroke 360 combos - 10/26/12 07:04 PM

If you put a 5000+ converter in it, does it matter what it makes for tq at 3500?

The tti headers will make more midrange tq. At 5K+ there isn't going to be much difference between the tti steps or 1 3/4" super comps. Either of those headers are going to cost some $.

I know it's not a 360, but it makes the point regarding headers. See test one and two. Not much difference in the two set ups. If fit is a concern then you make a choice based upon that consideration.

http://www.carcraft.com/techarticles/ccr...seline_1_2.html

A 1.8 throttle plate allows for a 1 3/4" 850 baseplate which should allow for a 4150 950+ mainbody.

Hey Rob, thanks for chiming in

Because I am new to the automatic stuff, I really don't know all much about them. Im assuming with a 5000 stall the car will stay pretty much, what, above 4000k throughout the pass even after shifts?

If that is the case, which I never even though of, would not a single plane be of benefit for the higher rpms, as well as the bigger headers? Yes, both the hookers and TTI's are costly, but the hookers are still more affordable, not to mention there are alot more used hookers kicking around (gosh that sounds wrong

) than TTI's from what I have seen.

In that test Brian did with the stroker the stepped headers were better, but what can I conclude for that in my motor?

As for the carb, the whole 950 not being a true 950 carb has always confused me. Here are the rules for carburetors word for word

CARBURETORS: Any standard design type carburetor up to, and including 750-cfm, with a maximum throttle blade size of 1.800� permitted. Standard performance carburetor modiﬁcations permitted, including removal of air horn, internal and external modiﬁcations. Split carburetor prohibited.

Also, the class is more than likely going to be a pump gas only class, which should keep things more realistically competitive for a heads up deal.

If I can get the best engine combo and converter sorted out now, and then after testing if I need more gear just swap that, it would be ideal

Re: 10 sec stock stroke 360 combos - 10/26/12 07:37 PM

IMO, you wouldn't notice any difference between either header because when you hit it, the engine goes right by the range where the tti were a lot better 3-4K. With a 5k+ converter the engine should never be running below flash speed anyways. Makes the 3-4K numbers unimportant.

Another thing on headers. I've never seen the huge gains that some people spout about on decent hp 400-500 sb's. One was in the 40hp range on a 450hp engine... never seen that myself. I have seen this progression on a 450hp 360. Baseline with Hookers 1 5/8, dougs + 4, super comps +9, tti +9.

I would not put a 1 7/8" header on your car.

The carb thing is the baseplate has a 1.75" plate and the venturi size is 1.375 or something like that on a 950hp. If the baseplate has a 1.75 plate, you can open up the venturi size, which = more cfm... Look the holley numerical listing and see how that works for baseplate/venturi and ratings. Especially in the 4776-4780 and 4781 numbers.

So you would keep the 1-5/8's that I have now for headers then?

What about for intake manifold- if this thing is going to be spending its time upwards of 5k, would it better to go with a single plane even though the air gap makes good power to 6500?

As for the carbs, I see what you are saying now. But with the class limiting to 750cfm, by opening up the venturi size am I not effectively going larger then 750cfm of flow? or is there no way to police that since all they can measure is the throttle blade size and make no mention of the venturi size?

Posted By: RobX4406

Re: 10 sec stock stroke 360 combos - 10/26/12 07:55 PM

I'd put a different header on it. Either supercomps or tti.

Intake, not sure where you plan to spin it. My first choice would be a victor 340. An Air Gap with a 1" open spacer will run well too if you already have one. You could also mill the divider down a little... never tested that on an Air Gap, worked OK on ld340's.

The way I read the carb rule is the throttle plate/baseplate size is your limiter. The mainbody venturi is not addressed. Nor is a 750 carb from holley usually a throttle plate that large, they are usually 1 11/16", less than 1.75"

Supercomps hang below the centerlink, or do they go above it?

Im thinking 7k will be the max?? but not 100% sure yet. I do have the air gap with the 1" spacer right now, but no milling of the center divider has been done. I guess im im going over 6500 its best to go single plane?

As for the carb, I will have to look into what will work better then

Another stock stroke/iron headed 360 SuperStock Volare from the south central US has gone high 9's setting the SS/JA record(it went straight to the barn,tore down and deamed 100% NHRA SS legal).

I know these two combo's/engine's are far from streetable with deep gearing,high stall converters and race fuel..but don't let anybody tell you you can't make good horsepower with a 3.58 stroke 360..not going to BS you and say its cheap and anybody can do it..but its all about making the total package work together!

Just saying it can be done without NOS etc..10.90's and streetable is doable.

what do you guys think- with the 4.10's and 26" tires, does this thing need the low gearset in the 904? or is the standard gearset workable?

Standard is fine.

You don't think there is anything to be gained by swapping in the low gear set? Seems like my combo fits the low gear set perfectly (heavy car, low torque)

If you can hook it, theoretically it should work better. A 360 is still going to make decent torque and I don't think it will be a drastic change.

With a big converter, maybe a few hundredths to 60 foot, I don't think it will be a night and day change.

My only back to back comparison with the low gear vs standard is a swap from a low geared 904 to a 727. It slowed down the 50 about .06 and the over all ET about .2-.3. But, that was a swap to a 727 which is heavier etc etc.

anyone else care to comment on the low gear with the 4.10's, 26" tire, and a 5000+ converter? I know it should definitely help the 60's, but im also worried at the same time with that little tire and that much gear, it might actually make it harder to hook? That, and the rpm drop into third gear from second also

Thanks for the plug...yes..my daughter drives the 71 Dart, has run a best of 10.91 in Vegas over the labor day weekend. Her car is currently get 4 wheel disc brakes with RMS upper control arms and adjustable strut rods..

And I got my 71 Demon to Sacramento Raceway back in Sept...It has a 360 that is similar to the Dart's engine, probably a got 10-20 hp less...and it ran 10;72 @ 120.66..the mph was down i felt but it ran consist.

...Tony, anything in my combo posted above that you would change/ recommend to hit my attempted goal?

Its already on my Christmas list

I wanted to put a Jerico Dr-4 in the car, but could barely afford the trans and shifter- the clutch was going to be close to another thousand bucks, and I just couldn't afford it. My 4 speed stuff was worth more in one peice then it was scattered
