Here's the combo, what do you think? I know the downfalls in the combo for what I want to do with it, but as it sits, what do you guys predict?

360 smallblock chrysler stock stroke .030" over KB pistons 10.5:1 CR with 0.040" quench
IMM prepped RHS iron heads flow peaks 271 at 550" on the int, 190 at 550" exh
Bullet hydraulic roller cam 243/251 at .50 duration, lift is 562/562 on a 109 LSA with 4 degrees advance ground in on a 1.5 rocker (not sure if i should step up to the 1.6 and getting 600/600 out of it). Exh lobe is considering light nitrous use in the future as well
Was told rpm range would be 1500-6200, but possibly higher?

Edelbrock RPM air gap port matched with a Holley 750HP on top
1-5/8" headers into a 3" exhaust with Borla race mufflers and x pipe

The car weighs 3400lbs with me in it and is getting a dana with 4.10 gears
Car has a 28x12.5 ET street bias ply and has the full caltrac setup out back, with calvert 90/10's up front, 6cyl torsion bars and adjustable upper control arms

Transmission is a a chrysler 4 speed 2.66 first transmission with a centerforce dual friction clutch and a v-gate shifter with two step (hopefully will help with consistency some and not missing gears)...Im a pretty good driver and at the track the gas will be matted 110% of the time


lets hear it! hopefully my hopes for it are close to what it should run

the weight is what concerns me, i would say at 3000lbs thats a 10 sec car, at 3400 id say 10.50-10.70

11.70's NA

mid 11s

ooops i meant to say 10.90's at 3000 then 11.50 - 11.70 at 3400

work on the weight man.

Your weight is about 100 lbs lighter than a Challenger I had and with a much more tame 360, I went 11.70, but I had 4.56 gear, 28x10.5 slicks, auto, 3500 converter, home ported stock heads, .540 flat solid, 9:1 compression.

If you can row those gears, I would think 11.4's.

12.000000's on a good day.

4 speed...

how good can you shift?

and getting the car to launch without bogging it.

The motor is gonna make enough power to push the car well into the 11's. Whether or not you can do you job will be the biggest factor.

12.10

I'm thinking you could go easy 11.40's if it hooks, I ran 11.70's all night long with a 4 speed a-body with a W2 340 isky solid.....30 years ago.

Cam spec's look good for what you are doing, I like the 1.6 rockers.

Spun it 7200, eventually 7800 going to 4.56 gears....big block boyz HATED me back then

I doubt my old first get W2's flowed much better than your RHS's, I was barely 18 and all I did was a bowl clean up and VJ on them. I eventually got them worked to flow around 290. When I detuned it to my daily work car it still ran high 11's switching to 3.91's and an ultradyne hydraulic 231/239 flat tappet.

your ET is going to be in the 60'....if you get a 360 to hook just right you just row it through and she'll et.

Didn't understand your open/seat comment...did you mean 150 on the seat?

You don't need to shim the lifters...run the heads they way you get them and run the lifters untouched.
Run 10w40 oil and let it eat. I've run hyd. rollers with our RHS heads up to 7000rpm and still not had any lifter pump.

I personally think 11.90s. If it had a stroker crank id say 11.40s.

13.30

I think it should go 11.50 or better pretty easy.
You weigh 500 more than mine and have enough power there to at least run a tenth better. Check my sig.
