383 stroker rwhp, Help ???

3 or 4 questions to help with my 2003 Zo6 : I NEED SOME FACTS
Going with 383 Stroker kit.

1) What rwhp/tq are you guys getting ?
2) What cam grind ?
3) Is is still very streetable ?
4) what kind of 1/4 times if you run it, and sixty foot ?

I'm trying to get a very rough idea on where I will be with my 390 gear. Heads will be AFR 225 or comparable, 90 mm ported fast intake.
I was at 433rwhp with 400tq before on stock bottom end , AFR 225, 90mm Fast, 342 gear and baby 224 cam.

Re: 383 stroker rwhp, Help ???

1) What rwhp/tq are you guys getting ? 478/440 after some miles
2) What cam grind ? 236 585 112
3) Is is still very streetable ? Yes & about 28 MPG HWY with 3.90s
4) what kind of 1/4 times if you run it, and sixty foot ? Best yet was 11.610 @ 123.55 with a 1.80 60'

I've got 14K miles on the 383 and no problems so far.

Thanks Dan,
Putting package together now. If I can add 50-60 rwhp with this stroker kit and cam things will be great.

Re: 383 stroker rwhp, Help ???

You're welcome, Pit. You'll definitely feel the extra torque and with your 1/4 mile skills run 10 sec passes

Since there's so many cams to choose from it might be a good idea to talk to the guys @ LPE, 21st Century Muscle Cars or Alan Futral @ Futral Motorsports to name a few.

Good luck and keep us posted on the build.

Well Zo6Phile,
not much happened on the build yet. Delivered the Z to Tracy @ Rev-Extreme. Going with a 383, cam is a custom 236/244 612, their heads and ported TB. Also had my Fast ported. My hope is to have a mid 10 second car in cold air. Also going with new McLeod Twin and steel fly wheel (had RPS Single & aluminum before). Fingers are crossed !!!

Pit
