Budget 360? - 05/05/10 04:40 PM

Looking to start collecting parts for my 360 build. I'm not looking to make a ton of hp but I want the car to get down the track. The only things I want out of the motor are: must run on pump gas, hyd. flat tappet cam only, Iron heads, no strokers and no $500 pistons. I want to make a reliable 400hp. I have 3.55 and a 5.38 geared center sections to work with and the trans will be built with all CRT parts...

KB107 pistons, stock magnum heads (or the enginequest 318B's hughes has on their website for $699/pr assembled with springs good to .540" lift), stock magnum rockers, headers, eddie RPM air gap, 750-800cfm carb, headers, and a comp magnum 280H will make that much power

I'll sit down later and post my build it's exactly what you are asking for. Just finished it up about 2 weeks ago. Hopefully I will be healed up enough in about a week to start putting it in .I had surgery about a wk and a half ago.

I second Patrick's combo. The only thing that I had any different was an Edelbrock Performer Rpm cam and went 12.0 @ 114.

What he said...you'd probably exceed your 400 HP goal.

There are many hydraulic grinds out there that can get to your power goals and then some. Match one the the compression ratio, converter and gears and off ya go!

I'll add a couple of things about those Iron Ram heads. First, we have a pair of EQ's we're going to play with on the flow bench. (Although we got them "as cast" rather than prepped from Hughes). We popped in a 2.02 intake to compare with a pair of 2.02 RHS/Indy heads we were doing at the same time. Interesting to note, they showed slightly better flow than the RHS's below .550" lift.

The other cool thing, for a low dollar street/stripper are the Magnum rockers: Keeping a lid on lift (you can only go about .530 without trimming the guides anyway) and spring pressures the OEM 1.6 rockers will suffice well. Further, if you do want to increase lift on the cheap? V10 (truck) rockers are 1.7 and are a direct bolt on!

Keep us posted on what happens will ya?

So I would be able to run a .508 cam with no machine work to the heads? If I can do that I'll just stick with the magnums. I have a buddy that has a set of stockers for $100...

remember, the mags have 1.6 rockers, which make the .508 into .541" lift. with my OEM magnums, using 2.2L retainers and hughes #1110 springs with the magnum keepers, I had about .510" of available lift before I began getting too close for comfort to coil bind and seal to keeper interference. when I had the valve job done, I had the valves sunk about .030" to get a little more clearance. I'm running .506" calculated lift with mine. a comp magnum 280H will be a calculated .512" lift with the mag rockers, and will have lift/duration specs pretty close to the 380HP crate motor's roller cam.

Yes, but you'd have to trim the guides. Although it's been published at .530 max lift, I'd use .520 for an extra margin of safety.

Rock Auto will sell you BRAND NEW stock rockers for less than $11.00 per PAIR, with the trunon (sp?) stands and bolts = less than $88 for all 16. Check it out.

3250, 3000 stall converter, 3.91 with 28X9 slicks

Re: Budget 360? - 05/07/10 03:28 PM

My 360 started as a .040 over Napa rebuilt short block. I took it apart to check everything. I had the block decked (deck .015 head, 63cc., gasket .028, compression 10.51)reversed the cast dished pistons on the rods and put in good rod bolts and had the rods resized. I put in an old Manley cam that I had. 443 lift [Email]224@.050[/Email] I don't remember the lobe seperation but I think it was around 108. I used J heads pocket ported with 2.02 int. valves and 273 adj. rockers an LD340 intake with a 1" 4 hole spacer and a Vac. 750. For exhaust I used heddmen 1 5/8" headers, 3" exhaust with ultra flows ending at the axel. I used a 904 with a Dayco 2,400 stall converter and an 8 3/4 with 3.91's the slicks were 8"x 26"x 14". Suspension consisted of 6yl. bars and comp. eng. adj. shocks in the front and 002/003 superstock springs with Mopar perf. 50/50 xtra long shock in the rear. The car was a 70 Valiant 4 door it weighed 3,320 with me in it. With an electric water pump drive, 5/16" fuel line with holley mech. fuel pump and a homemade fresh air intake (dryer hose and a dual snorkle air cleaner)the best run was 11.96/113 but it typically went 0's and teen's in decent air at Atco and E-Town. Typical 60'was low 1.70's

Re: Budget 360? - 05/07/10 04:07 PM

Good combo JC put a better converter in and the ETs will really drop. Years ago I had an old 318 in my car while my 340 was being freshened, nothing special just 360 heads it ran 13.20s with 3.91s and a junk 10 inch converter, I put in one of my T/A 8 inchers and started going 12.70s. BTW my old backup motor before I broke it: 30 over 340, 9 to 1 comp with ported J heads and 557 lift M/P cam went 11.30s in my combo.

Re: Budget 360? - 05/07/10 06:33 PM

Thank's 11sec. That combo is in a 70 Duster now but with a 727 a 10" Dynamic conv. 3,200 stall, clutch fan, no fresh air and it's 90 lbs. heavier but still the same 360 that's been together since 96. Best it's gone so far is 12.71 on the brakes (semi's in Pro last year Mopars @ E-town). Unfortunately it has slowed down since then due to 2 cam lobes on there way to going round. So now it's time for a freshen up. No racing at the Mopars this year!

JCCuda: That's the most impressive thing I've seen in a long time. I remember seeing the car in a magazine shootout ages ago but looks like it got a lot faster. Very impressive for such a modest combination.
Posted By: JCCuda

Re: Budget 360? - 05/08/10 11:21 AM

Thank's JDG68, When it was in the High Performance Mopar it had a 100,000 plus mile 360 with the cam I mentioned in the earlier post but with the 100,000 mile valve springs. It used the same headers, intake, conv. and rear gear. The suspension consisted of worn out bushings and shocks in front and worn out leafs with the rear clamps off and a pinion snubber on the rear. The exh. was 2 1/2" to the axel with cheap turbo mufflers. I think the fastest that combo went was 13.20 @ about 101. I bolted on the pocket ported J heads with new springs all else the same and the car went 12.87 @ 105. After about 12 passes one of the crane valve spring retainers broke in half, it dropped a valve and put a hole in the piston. That's when I put in the engine described in my first post. I think the first pass on the combo in the previous post the car went 12.30 something. I always thought with the right converter (to 11sec's. point) and some more tuning it would've gone 11.70's-80's but the no rollbar cutoff when I was racing that car more often was still 12.00 and I didn't want to deal with the nonsense of new belts every 2 years a fire jacket etc. As a side note that 100,000 mile short got a piston from another used 360 fresh rings and bearings a 340 blueprint cam with a cast 4 bbl. int and went into a friends Demon with 2.74 gears and went 13.67

Seems as though those J heads are popular .... how about the X heads ? How about pistons ? ... in a motor that needs rebuilding. OEM budget cast or aftermarket budget cast, hyper or forged ?

A N D .. how about balancing the assembly internally? .. worth the effort and expense?

Really little if any difference other than the casting number and the X's have 2.02 valves and most of the 915's had 1.88 valves which is not a big deal unless you are going to be spinning in the higher RPM range in order to utilize the larger valve.

The 360 Edelbrock RPM package (cam,heads,intake,3.73 gear) is able to take down 14 flat in a 4000lbs diplomat. After a year of tunning and going with a higher stall.

The RPM package from edelbrock takes out the guesswork. You know what you are going to get . That it will kack the wack it was built to. Works together like magic. Wanna be really crazy ...hit it with a 100 shot. EEEHhhWwweee! 13's for sure'

Our 410 we did for CC made 485HP and 517 TQ with our RHS heads, no porting, pump gas and a hyd. cam.
So a 360 with same heads, intake, smaller 275HL cam and 9.8:1 should make 430-440HP with no other changes.

Re: Budget 360? - 05/13/10 04:20 AM

I think alot of times this weight of cars gets tossed around without hard evidence, not saying the M bodies aren't heavy from the "factory", but in most cases, if you start building & drag racing them, you've somewhat lightened them up by stripping parts.
Posted By: dOc …

Re: Budget 360? - 05/13/10 04:36 AM

I realize that an M-body is going to be heavier than a 4 dr A body ... but 900 lbs ?

OK .. the FRONT seat weighs 50 lbs more? .. rear seat 10? ... door beams - 40 ? ... bumpers with the beams (MORE than the A body) - 40 ? Electric windows...30? ..Xtra insulation and carpeting diff ? .. 40.

I would HONESTLY like to know. I have always liked the idea of a 5th as a SLEEPER project with a BIG B engine ... but there are major issues with that ... that being a decent exhaust system.

CAN'T be done.

Sooooo ...an A engine IT IS !

40lbs here, 50lbs there adds up quick. don't forget, an M is closer in width to a pre-71 B than an A.

my 5th ave was 3950 with 1/2 tank of gas, without me when I was dropping off some scrap at a metal recyclers, without the scrap in it.

the weight adders to mine:

A500, 1" rear sway bar, 5 leaf rear springs, 1.125" front sway bar, 11.75" brakes, 8.75" rear

the weight reduction:
aluminum intake, loss of smog pump

the weight wash:

17x8 mustang rims w/255/50R17's vs. steel 15x7 with 205/75's, headers and 3" big single exhaust vs. stock manifolds and thick walled 1.875" exhaust with 3 cats.

realistically, I'd gather my 5th, stock probably was 3700-3800 lbs. the sound deadener under the carpet is HEAVY. the bumpers are, too. the interior door panels have a fair amount of heft to them, too. the front power seats are quite weighty....

a big block in an M is quite roomy, if you stick to a low deck, and/or use a K car power brake booster. the huge booster in them makes even a small block snug. as far as room for an exhaust, headers aren't a problem, the rear, you can fit a big single (3") over the axle pipe, or move the tank over, and you can fit dual 2.5" tails....there's enough room under the car to run the large body dynomax (5x11x20" case) mufflers under the rear seat.

Boy oh boy will you want to be a fly on the wall of my shop for the next couple o' weeks. I just broke in a customer's stock stroke, pumpgas, hydraulic flat tappet, dual plane 367 (.040" over). He wanted 400 HP and I just broke it in and did a very short pull from 3500-4200rpm. Torque is GOOD as usual 402 lbs the whole run. Nothing is optimized yet and already making 321 hp @ 4200. Ran out of fuel and time but will update Tuesday. Also will be running a EngineQuest MAgnum headed 367 in the next two weeks as well--Can.t wait for that. J.Rob

Re: Budget 360? - 05/16/10 01:42 PM

When i bought my RHS heads from hughes, the EQs were on back order, you may want to call them & find out if they have them now, But you might be better off with the RHSs for 175.00 more, they flow 10cc more OOTB then the EQs, there also more benificial in the long run if you plan on doing any milling or porting, i will say i'm very very happy with mine just basically OOTB with the 1.92 valves & there 1110 springs, but i'm limited on lift.

These are the iron rams

Re: Budget 360? - 05/19/10 01:23 AM

So I promised to post results Tuesday and here they are (if anyone cares). The rundown on the build is: 367 ci .040" over KB 107's
"0" deck, Stock rods ARP bolts
stock crank cut .010"/.010"ext balanced
Lunati VooDoo cam # 60404 hyd flat
234/242 @ .050" installed 105 c/l
"J" heads PP w 1.94/1.6 Chev valves
flow was 229 cfm @ .485" N/C to .525"
stock rockers and shafts/pushrods from
1970 Ford 302 application
Crosswind dualplane/ 750 Proform dbl
1 5/8" street style headers (you know)

So I put it through it's paces this evening on our Superflow 902 and here's how it went. Installed the new pushrods--torqued down the shafts and fired it up--sounded good and normal. Put some heat into it- set timing @ 36 total,dialed in a pull from 3500-5500 and let it go. 383 hp @ 5500 406 lb/ft @ 4100. Not half bad for what's in it and that is nothing (is what I think anyways) What's really nice is that the torque came in @ 400 + right from the bottom. Next pull I fatten up the carb a bunch and dial in a 5800 upper rpm limit---391 @ 5700 416 lb/ft @ 4100. This is all with an in house 650 Holley and a 4 hole tapered carb spacer. Next we remove the 650 Holley and spacer and put the customer's 750 Proform on with no spacer--Wow 383hp but 430 lb/ft! at the same peaks--the averages are quite good at this point. Next test we add a 2" open and hp surges to 394 but torque is down in the 416 range but is showing quite lean on the AFR. Jet it up 4 sizes all around and repeat-400.3 hp and 423 ft/lbs. Not bad but I would minus the spacer and take the 430 ft/lbs if it were mine.All in all the customer spent about $2700 total and now has an engine that should get her Duster into the 12 s. I will post some dyno sheets for those that are interested. What is really nice is that the torque peak occurs @ 4100 rpm and the hp occurs @ 5700--that s a 1600 rpm spread. I should add that we turned it to 6500 rpm just to see how much hp would drop off and it only fell 20 hp--remember this is a hydraulic flat tappet. Idle vaccuum @ 800 rpm was 10.5 and stable. I think the customer will like this engine. FWIW J.Rob

Not half bad for what's in it and that is nothing (is what I think anyways) What's really nice is that the torque came in @ 400 + right from the bottom. Next pull I fatten up the carb a bunch and dial in a 5800 upper rpm limit---391 @ 5700 416 lb/ft @ 4100. This is all with an in house 650 Holley and a 4 hole tapered carb spacer. Next we remove the 650 Holley and spacer and put the customer's 750 Proform on with no spacer--Wow 383hp but 430 lb/ft! at the same peaks--the averages are quite good at this point. Next test we add a 2" open and hp surges to 394 but torque is down in the 416 range but is showing quite lean on the AFR. Jet it up 4 sizes all around and repeat-400.3 hp and 423 ft/lbs. Not bad but I would minus the spacer and take the 430 ft/lbs if it were mine.All in all the customer spent about $2700 total and now has an engine that should get her Duster into the 12 s. I will post some dyno sheets for those that are interested. What is really nice is that the torque peak occurs @ 4100 rpm and the hp occurs @ 5700--that s a 1600 rpm spread. I should add that we turned it to 6500 rpm just to see how much hp would drop off and it only fell 20 hp--remember this is a hydraulic flat tappet. Idle vaccuum @ 800 rpm was 10.5 and stable. I think the customer will like this engine. FWIW J.Rob



if you had unlimited funds, the next neat step to try would be to get some OOTB or lightly prepped RHS X heads and toss on the short block (hughes sells them for under $1k/pr). you'd get smaller chambers to give you another 1/2-3/4 point of compression, as well as about 30 cfm more flow at the same lift point.....or even some EQ318B's--you'd get more lift using the magnum rockers, and while OOTB published specs look like at best you'd only have a 5-10 cfm flow advantage with them, the additional compression and better port velocity (flow about the same as your prepped J heads, but with a smaller cross section), while you may not pick up much in the way of peak HP, I'd expect you'd probably pick up another 10-20 lb-ft of TORK!

also, from a curiousity side, it would be interesting to swap the crosswind with an eddie RPM air gap to compare back to back...

I would think that would get the car into the 11's and with those torque numbers it would seem there is more power lurking there too.

stock rockers and shafts/pushrods from
1970 Ford 302 application


What the heck??? Aren't those a stud app like a 289 or SB Chevy?? But with J heads????????

Please explain...

I think he meant
-stock rockers/shafts
-pusrods for a 1970 ford 302 app

which also doesn't make sense, as an LA flat tappet uses a 7.5" pushrod stock, and a 1972 ford 302 uses a 6.876" PR....

that would be close to the right length for a stock LA hydraulic roller cam (6.76" stock)

No I meant the pushrods are for a 1970 Ford 302 app 7.565" in length? Hey they work and work well. I do have a new update that is not so good news. Upon removal from the dyno I removed the distributor and noticed a copper flake on the lifter valley wall (Uh oh). Tear it down to find number 8 rod bearing burned up. It appears the number 5 cam bearing may have had something to do with it. Oh well thankfully there was zero other damage and is on its way back together. Will post the part 2 results later this week. I wonder how much power was being eaten -literally? Probably not much but we'll find out. J.Rob

That's an 11 second engine in a good chassis at 3200 or so.

It should run low 12's all day long without a struggle.

Just as a matter of fact--This engine was run with the 8 quart Milodon with NO windage tray. I think I will install a windage tray and see what happens--What do you guys think? Any opinions or feedback on using a tray in a small block? I will find out for myself either way but would welcome some input. I am also going to try some header extensions as well. Should be very interesting or anti-climatic. J.Rob

A tray is always worth-it ......

.... EXCEPT when using a scraper in a dry-sump system !
