dyno'd my 402
466 rwhp and 424 rwtq on a dynojet with a fully built Turbo 400 trans and 3500 stall converter. the read end is a Strange 12 bolt with 33 spline axles, 4:10 gears and a spool
the mods are as follows >
11.1:1 cr
LS2 block
Callies Forged crank
Manley Forged rods and pistons
AFR 225 heads
LGX2 cam (112 lsa)
Yella Terra 1.7 ratio twin shaft rockers (not the ultralites)
Fast 102 manifold/92 mm throttle body and fuel rails
57 # LS2 injectors
Racetronix 255 Lph fuel pump
Lingenfelter 100 mm MAF
FTP 104 mm lid
Hooker 1-3/4 headers
Dynomax bullets dumped under the front seats with no cats
HP tune
27* timing
NGK TR6 plugs gapped at .035
100 octane unleaded Torco
i got a dry nitrous kit in the car but have not dyno'd the car with that yet. the nitrous should bump the peak hp up 250 rpm....
as you can see from 6,250 rpm's to 6,500 rpm's the HP curve noses over as a result of the heavier rockers. but i feel the added valvetrain stability will help once i spray the car. we shall see....
i will redyno the car next year with the juice and see what she does

this was a crate motor that i bought and it had a Bigger cam in it that was not nitrous efficient so i put a nitrous cam in it. i will eventually spray a 250 shot via 2 kits and raise the compression and put a Bigger custom nitrous grind in it after i get the car dialed in at the track on the bottle with just a 125 dry shot. i will also get my manifold ported and get a bigger throttle body and bigger headers to go with the bigger cam in the future too

with the trans brake i plan on putting in i should be able to get into the 10's on the motor at my local track despite the HIGH DA. as you can see in my sig i ran a 11.18 with the LS1 motor that i used to have in the car, but that was with a 100 shot of nitrous sprayed in 2nd and 3rd gear. i should be able to run at least that quick now on just the motor off the foot brake at a 4000 foot DA
