Post your 360 engine combos - 11/11/07 01:13 AM

I am looking at having a 360 built as my 318 just lost a rod. It will be a stock block, mostly street driven and once in a while a strip car. Looking for something that is reliable and daily drivable. Have at it boys

Regular gas = Maybe 8 1/2 to 1 compression ratio, .455 lift, 214 dur. cam. Or a little stronger than those if ya want better times at the strip.

Re: Post your 360 engine combos - 11/11/07 01:41 AM

I was looking at no more than 9.5:1, no bigger than about a 500 cam, (might go with the smaller thumpr cam), worked 360 heads, etc

Buy the Summit Racing rebuild kit for a 360.It has good pistons (H405P's),good gaskets,good bearings,and a good price! Buy a Crane 150052 cam and set it at 4 degrees advanced.Use an Edelbrock Performer RPM,RPM Airgap,or an LD340 if you can find one.Use a 1" 4 hole spacer under the carb,and use a decent ignition system.Use stock 360 or Magnum heads with a good 3 angle valve job and good springs matched to the cam. Here's what not to do

Don't use KB107 pistons,because they will give too much compression for a street motor.Don't use the cheap Chinese Air Gap intake...they are junk! Good luck kid,and sorry you blew your 318 up.

Re: Post your 360 engine combos - 11/11/07 01:59 AM

Mine is a '79 360 with
Comp XE268 cam (224/230@.050, .477/.480)
Speed Pro H116CP pistons (9.66 CR)
80's "345" heads with 2.02 valves put in
Perf RPM manifold
MP Windage tray
Melling HV oil pump
Heddman 1 5/8 headers
Holley 670 carb

Good for I guess 340-350hp, pulls plenty of vacuum for power brakes and idles at 600rpm in my '80 Mirada I drive every day even through the winter last year. I think it's a great driver combo.

Re: Post your 360 engine combos - 11/11/07 04:01 AM

Sounds like you've got some key parts to swap onto the 360

One other thing you will need is a B&M flex plate to mate the externally balanced 360 to your existing convertor.If you plan on upgrading convertors while you have it apart,you can just get one that's balanced for a 360 and use the stock flex plate. I have a 360 built like I described,and it runs great in my 71 Challenger.It should run better in your A-body because it's several hundred pounds lighter than my Challenger.

Re: Post your 360 engine combos - 11/11/07 04:22 AM

A good one I had:

Never measured...the compression could have been b/w 8.2:1 although the guy said they were "9.0:1" pistons (but they were far down the hole...but I digress).
Stock 360 heads, 1.88 valves, 3 angle valve job.
MP .450/.455 cam, 268/272 duration
Edlebrock performer intake (better ones out there...this one was free).
Holley 4016 600 cfm carb, electric choke.
Hedman headers

In a valiant with 4 speed OD manual trans, 2.94 gears this thing started great, idle great in traffic, got as high as 25mpg if you really took it easy on the hwy (typical tank was 18mpg), and even better, went 14.2's all day at the track

This was in a 4 door 1976 valiant.

Re: Post your 360 engine combos - 11/11/07 01:52 PM

with a relativly stock rebuild I highly recommend the Crower 267 HDP cam with the springs to go with it. It has lots of drivability, vacume and has good low end. 267/272 adv. dur with 475/485 lift. A great little cam. Ust this with a good intake like a LD4B or LD340 with a 650 carb and you will be happy.

There's a cheap Chinese version of the air gap out there?Is there anything these guys don't try to copy. Who makes its and who sells it? guess I want to make sure I don't get one of these on my rebuild.

Re: Post your 360 engine combos - 11/11/07 04:00 PM

Here is my 360 build;

* 360, .030 over KB107 pistons at zero deck
* Magnum cylinder heads with 0.039" gasket
* Comp XE268H cam 224/230@0.050, .509/.512 with 1.6 ratio magnum rockers.
* Professional Products Crosswind intake. Don't believe the naysayers that it's junk and a cheap copy. It's no more a copy of the Air Gap than an M1 dual plane is of a Performer. Side by side it's obvious it's not a copy plus the casting finish quality is better than an air gap.
*I am using a Holley 670 Street Avenger and Hedman headers.

This engine is making around 370 HP based on 102 mph trap speeds in the 1/4. Has 10.6:1 compression and with the closed chamber magnum heads and ideal quench runs fine on 89 octane.

I have just shy of 20k miles on it since installing it in my 68 Barracuda in Jul 05. It gets 17-18 mpg around town and 21-22 on the hiway.

The only down side to the engine is the XE cam's aggressive ramps makes for a noisey valve train compared to what I would expect from a hydraulic cam.

A well built stroker 340 will keep up with that. Unless your going to spend a little more money, the stroker small blocks are an excellent bargain.

Kyle, the 360 you have spec'd out is very similar to my current set-up. You will need more carb though and a quick advance distributer. Power should be around 350 if you buy a better carb.

My current 360 combo is 484/284 purple cam, 9.5:1, stock 360 2.02 heads and airgap with a QF 750dp in my '78 with 4:56 gear and a low gear setted A500 OD trans. I also went to mopar quick advance distributer and added a 1" spacer under the carb. The stall converter is a tight 3000 and the engine would like a little more. I recommend a low gear setted 904 with a 9" converter around a 4000 stall and 4.10 or 4.30 gear.

Now I plan on a 416/340 with almost the same duration cam, but a solid with 1.6 rockers and final lift at the valve around 0.600". This should give me the same idle and driving characteristics, yet scream like a bracket engine. Still looking for a good set of cast pistons around 11:1 compression though. With the heads I am still undecided.

Meanwhile, my current 360 is going to get the 1.6 rockers, 3" exhaust and maybe a tunnel ram. I have two sitting around, but not the carbs.

true but where will he find a cheap 340?? anyway i was just joking around, trying to get another a-body guy to join the bigblockdart forum

i had a nice 360 too, here are the specs, it was a decent combo

360 mp shortblock, 10:1 - not sure if these are still available
.509 cam
rpm air gap intake
eddy heads
tti headers
750 DP carb

motor was strong but the 3.23s and the stock trans killed it, that was next on the list but decided to go big block when i realized it was going to come one day anyway, and the parts were about the same price. its never been easier to do this combo, and even if you can get a small block to get the same numbers, theres just something about a big block. whatever you do make sure you give some attention to the trans or it will be a dog

Your combo sounds fine to me. I wouldn't spend the money for the 2.02 valves unless you eed to reseat the valves and replace some anyway. For your set up you will gain absolutly nothingand posibly take away some of your low end. The bigger valves come more into play on in the upper RPM range which youwo't be using.
All the guys recommending this intake or that - why- you already have a great intake with the LD340. Use it. The Airgap MAY or MAY not be slightly better but not enough if any to be cost effective for you to switch. FWIW it is what is on teh Duster in my sig.

Re: Post your 360 engine combos - 11/12/07 05:58 PM

Above a 3000 stall, most single planes will more than out perform the airgap. I did blend the 1" spacer and clean it up a little, but I have a truck, and its shaped more like a brick more than anything, so I tried the air gap...So far, not impressed, but with a any other vehicle, it would have got a nice single plane.

My old '72 Cuda did extremely well with a 750dp, TM5 and a 2" open spacer all blended in. I also had a tight 8" 4700 stall convertor and a low geared 904 and 4.30's with 10x29's on it. Ran 12.0's all day with a 1.61 60ft and pump gas 340 with the 484 cam.

My 416 will get a single plane or TR, just not sure which one yet.

Gee! Every comparison test I have seen of the air-Gap and a single plane the single plane only started to have an advantage above 6000 rpm. And the Air-Gap had it all over the single planes below 6000 rpm.

I payed for this copied professonal products intake.. JUNK the intake bolts didnt line up with my heads..my stock intake bolted up just fine as well as my weiand intake, but not the Professional products.
This JUNK intake may look a little different then the eddy RPM airgap but none the less its copied with a few changes. spend the extra cash and get one that is made right here.. wish i did that the first time it would have saved me some time and SH to get a good one.

anyway there are a lot of good Combos here,

Id love to ride in the truck posted above, sounds like its Badd

How about getting back on topic.

Kyle DOES NOT need an intake as he already has an LD340. Whether the copies are junk or not is for another thread. Please stick with posting combos.

Thanks

Kyle you know my 360 combo pretty much. KB's, ported U heads, RPM performer, 268, 750vs, Dougs headers, runs OK.

The machinist/builder knows his stuff. He'll get you a good gombo that will work.

Maybe we shouldn't discuss anything and leave it all up to the 'builders'....If everyone followed your advice, no one would learn anything. I might be a tad off topic, and the out dated LD340 might be the best intake ever made, but there are OTHER options, and some work better than others in certain combos.

That may be true but the point is he already has the LD340. Which may be old school but it still ranks right up there with the new school and still demands top dollar.

I'd say with that combo, don't bother getting 2.02 valves. Just invest in a good three-angle valve job...and maybe spend the money you were going to spend enlarging the valves, instead spend on a little bowl work...not mandatory, but would be money better spent. Could go for broke and save up for some eddy's...

But a stock head, good compression 360 with a good cam like the compXE268, headers, good ignition and carb I would guess would put down an easy 350-360HP. Probably anywhere b/w 360-400ft-lbs of torque. If you saved up for eddy's, 400hp is very likely with the combo above.

The great thing about this combo would be that it's very streetable. It'd run great even with 2.94...since you've got the 3.21's, you should really be set.

I'd probably make sure I've got a nice 2200-2400rpm stall torque converter b/w it and the 904. Might want to go through the 904 and beef it up a little with good clutches, etc.

I'd estimate solid mid-13's at sea level. Very similar to my original combo in the heavier 4 door valiant, only with a better cam and more compression. Throw in the mix the weight advantage and better gearing...yeah, mid 13's shouldn't be a stretch at all, and decent gas mileage can even be had.

It won't be the fastest, but it's nice to have a drive anywhere, well manered older car that runs strong like that.

And the second combo you post would likely be in the 370hp range...410-420 with eddy's.

But be ready to go with a chrome box on the second combo...the orange boxes start pulling timing around 5000-5500-ish rpm's. Forget the exact number, but it was a noticable difference for me when I went a chrome box on a later combo.

Not the point of my post. I never said leave it to the builder and ignore all other input. Complaining about an intake manifold and it's quality is not what the thread was intended. It was beginning to turn into a byatch fest about chinese intake manifold quality.

Never said "leave it to the builder to make all decisions." He'll provide suggestions and it's the end users responsibility to choose. The guy potentially doing the build is real sharp. I personally think, if the buyer has an idea of what's desired, the outcome will be much better. In fact, the builders first question is usually "what are your performance expectation/needs?" People providing insight into what they have, how it runs is very pertinent to the "THREAD" and helpful in decision making. Sounds as though there are quiet a few people running similar style combos.

I've got a 360 roller motor that would be a great hard running street motor, but, totally inappropriate for a car that needs to be driven everyday as transportation as Kyle needs.

well my setup isn't nearly as Uber as some of the ones on here..but it's a decent budget build.

'76 360 block
.040" (don't know what pistons) but they are stock styled dish
compression i'm guessing around 8.5:1
reman'd heads w/ gasket matching (too poor for a shop to port 'em)
Crane 150052 cam 272H .454int. .454Exh.
about to pucker up for some Pro-Form aluminum rollertip rocker assemblies
Summit Air Gap Style intake manifold (works pretty good) with a 1" carb spacer
have 2 carbs i've been playin with on the truck right now is the Edelbrock 1406 w/ spring loaded needles and seats. The one that needs to be tweaked a wee bit and some more things added to it.. is the Holley 1850-3 600cfm.

For being in a lifted '76 powerwagon w/ 35's and 3.55 gears it still has some juevos.. but i'll see how it does with the new axles and the 4.10's..
for the budget conscious (retail prices):
360 .040" block - came with truck
Reman'd heads w/ gasket match - $300
Summit Intake Manifold - $179.99
150052 Crane Cam - $169.99

Here's the combo going into my '70 charger. It isnt together yet but here's what I have -

'75 block bored .040 totaling 367 cubes..
*kb107 pistons+moly rings
*78 or so 360 heads shaved .020 with three angle valve job.
*doube roller timing chain
*513/533 lunati voodoo cam
*weiand xcelerator intake+1 inch carb spacer
*modified and blue printed 750 holley vacumn sec.
*el cheapo set of headers I traded for
*windage tray
*summit balancer
*Externally balanced assembly using stock rods and crank.
*Accel distributor

Cant comment on performance at the moment but will keep updating. This will be linked to a 904 auto w/a 2800 stall and 3.55 gears. Hope this combo will be real streetable for the heavier body. Was going to use a set of heads with 2.02 valves, but didnt see that I would gain that much by doing so???

I have about $1600 in it so far. Good luck with your project..

Daily driver and for strip use? How clean do you want the idle? If you were spending my money I'd go roller hands down. Use the smallest one if you want to run manifolds or the smallest thumper edition from Comp if you decide on headers. Follow that up with the RHS iron heads, 0 deck Probe piston with a healthy dish which pulls the compression under 10 to 1 and slap on a thermoquad of your choice!

Here's mine....

360 .030" over
Stock crank .020/.020
recon'd rods /w ARP bolts
Forged Speedpro flat tops
Balanced rotating assembly

Eddie heads
XE-274 cam
9.5:1
RPM Performer intake
Holley 670 Street Avenger
Hooker 1 5/8" long tube headers

It has very good street manors and pulls 13" of vacuum.

I'm guessing 400 horses. Hope to see a chasis dyno next spring sometime. Click to link in my sig to hear/see it running.

I haven't seen this option thrown out here yet so I'll bring it up.

I just put a '98 5.9 Magnum in my '71 Demon and it runs excellent. Here is what I did:

Complete junkyard engine with 87K miles ($700)
Replaced stock cam with Scott Brown cam 226/238 @ 0.050" .520 lift. Was able to use existing roller rockers ($350-ish) (may be a little excessive for street)
3-angle valve job and machine valve guides down to accomodate lift ($325) (Wouldn't need with smaller cam)
New valve springs/retainers to accomodate cam ($300+)(wouldn't need this will a small cam)
RPM Air-Gap intake ( I know you already have an intake, you could drill magnum heads to accomodate)
Car oil pan/dipstick (you already have one)
Stock timing chain cover and water pump from LA block (you already have this)
MSD distributor (you should already have a dizzy)
Flex plate ($80)
Headers (you already have those)

Many on this board said that by simply using the stock bottom end on a 5.9 Magnum and replacing the cam I would have the exact same motor as the old MP 380 horse crate motor(these have the same crank/rods/pistons as the stock truck Magnum motors) I went with a little more cam than the 380 horse crate motor so I'm thinking I have 380-400 horse.

For $1000 (using smaller cam then I did) and your existing parts I'm thinking pump gas friendly with ~360 horse

Have at it boys

be sure & have your machinist get .040" quench in each hole (thats why I love full floaters for ease of repeated dissassembly/mockup) so you can run the most CR possible with your cam choice and todays lousy gas. CR (squeeze) is power!

Home made highflow water pump (disk on impeller)
HP 440 Carter AVS carb

On another post, they said a 340 looks different than a Magnum...

You tell me, is this a '68 340, or a '74 360 with Magnum heads???
