502rwhp/437rwtq 347 c.i. AFR 205/Fast92/TSP 1x7/8" Quick run down of the combo:
347 c.i. forged bottom end
3.905" bore
3.622" stroke
6.125" rod
AFR 205cc heads milled to achieve 11.6-11.7:1 compression
Cometic .040" head gasket 3.910" bore
7.350" 5/16" diameter .080 wall push rods
Custom 239/246 .624/.595 110+2 Tick Performance Camshaft
Morel 5315 roller lifters
Custom 4" induction system with 4" Vibrant velocity stack
Built 4L60e trans
Yank SS3600 stall
3.73 gears
9" rear end
SD Tune by Shane Hinds@Craven Perfomance
Locked:
Unlocked (don't mind the torque spike):
All numbers were backed up for accuracy, and because frankly we didn't believe them at first!
This car has been very fast already with 50+ less hp/tq(10.8@126 and 10.1@135 on a 100 shot, 9.8@138 on a 200 shot). It should really haul the mail now!

Thanks for the link to your CAI. Very well done. One thing though from the other thread.
"Don't mind the Tq spikes with the converter unlocked
47 Hp gain locked and unlocked"
Was there a 47 hp diffence between locked and unlocked? Or maybe the spike has something to do with the difference? That just seems to much for a lock and unlock converter.

Shane was referring to 47hp gain from the old set-up to the new set-up.
The spike has to do with the unlocked converter flashing hard on the dyno and screwing with the tachometer lead and registering a false torque reading.

What matters most in this combo is the average power it makes in its operating range. Over 400rwtq for 3000rpm and over 425rwtq for almost 1700rpm.
Not to mention that this was done without a ported Fast intake, without having to hand port the heads, no electric water pump, no fancy exhaust, no 6 speed trans and no hero runs on the dyno.
Plain ol' N/A HP at it's finest.

Great power! Pretty good tuning for idle too with 11.5 btdc intake opening. I'm thinking about building up a budget 403 short block for my c5z and have a similar top end already.
