So I was reviewing old posts, and can't seem to find any info on dyno results with heads/cam/intake on a stock displacement bottom end. So first off, if anyone has heads/cam/intake setup on a stock or nearly stock displacement, please chime in!

Here's what I plan on going with:

The short block I have in now is bored .040 over with stock compression using hypertenuic pistons.

AFR 190cc heads with 2.05/1.6 valves, 58cc chambers. Flow numbers are:

Lift Intake Flow(CFM) Exhaust Flow(CFM)

0.100" 51 58
0.200" 136 98
0.300" 191 136
0.400" 230 163
0.500" 253 177
0.600" 254 190

To that I'm going to add a comp cams CCA-08-503-8 which has a 224/230 duration at .050 with a 112LSA and .536 intake .544 exhaust lift with 1.6RR

I'm also going to add a converted LT1 intake.

Right now I have 1.6RR, Hooker headers, 24lb injectors, AFPR, flowmaster exhaust and the other basic bolt ons.

What kind of RWHP can I expect? What track times could I hope to see. Have a 6-speed with 4.11 rear gears. I want something that will get me into low 12's...possibly high 11's. Would this combo do it? What intake could get me there....HSR, LT1 conversion, superram?

Would I be able to achieve almost the same HP and gain more torque going with a superram as opposed to the LT1? What about the HSR (though this would require modding as it is on a corvette)

Finally, is that a good cam for a LT1 intake, or is something else better? What about if I would go with a superram instead...what cam would be best for that?

Thanks!

You should be able to get around 350 RWHP and 350 RWTQ with the LT-1 setup and I believe you should be in the mid to low 12's in the 1/4 once it is tuned. I also believe you would see close to the same HP with the superram and more torque with the superram. The car should be a little more street friendly with the superram but either intake will perform well on the street.

The engine listed in my sig was first in my 1986 Vette and it ran a best of 11.81 at 114 MPH, typical times were low 12's in the vette. Now in the f-body it runs typical times of low to mid 12's.

I believe the cam you list in your build up will work well with either intake. It has similar specifications to my cam 226/226 on a 112 CL with .559 lift with 1.6 rockers.
