Default ordered 402 stroker kit.. Dyno guesses on new setup

Well my old motor took a **** #3 cylender from a Nitrous pass over rev
New setup
ls2 block bored 4.005
Callies compstar stroker kit
wiseco 5 cc dome {13.3 compression @62cc} rings gapped 28 /30 for spray
prc 227 heads
still deciding on a cam
fast 102 intake/Tb
tsp 1 7/8 Lt's
Fti 5k SST converter



Car is track only so decided to bump up the compression and run c16 ...... what u guys think this should put down on a mustang dyno thru a th400 9 inch. NA

Also lookin for cam suggestions . was lookin at either the tsp texas giant or the btr 251/266 nitrous cam.

My 346 with tfs heads
, 235/242 cam and fast 102 did 450/430 on a mustang dyno. With a th400 and 9in. So I think you should be a good bit above that. Why are you going to keep the fast 102 on a track only car? You could pick up a good bit of power a single plane and turning some more rpms

Cuz im on spray and i already bought my nitrous plate set up for the fast 102. and i literally just spent 1300 on the intake/Tb 4 months ago so u can bet im going to get my money's worth out of it lol

Depends on how efficient the stall is. I would figure at 5K it will probably be pretty efficient. Maybe 90%. I would say in a 6-speed through the 9", that's a 530rwhp motor setup with the BTR Nitrous Cam/PRC 227 combo on pump gas... at 13:1 and C16 with more timing is probably more like 550rwhp. Converter being 90% efficient would mean 495rwhp or so. If those heads were the 237s or 247s, I think you could probably add 20HP to those numbers.

yea i agree bout the heads. but i talked to tsp and was told that i wouldn't really see that much of a power increase for what i would have to spend on a bigger cc head. i wonder if i could send out my 227 heads to be machined to a 237/247 head.
