488 hp/422 ft-lbs all motor LS1 346
See the video below, sorry it took me a second to notice the dyno computer screen was out of focus...but at least I did notice.
DYNO
IDLE, cutout open
*Notes: dynojet dyno, 93 octane, speed density tune, and I'm running 4.10s so that hurts me a bit on the power. Maybe with 3.73s and an underdrive pulley I'd have 500 rwhp.
cutout open: 488/422
cutout closed: 476/416
Mods
Advanced Induction CNC'd 243s
Advanced Induction custom grind...230/234 0.604/0.604
Yella Terra RRs
FAST 102, Tony Mamo ported
Fast 36 (42) lb. injectors
NW 102 TB
FTP 102mm lid
FTRA
American Racing 1-7/8" headers, Y-pipe
Borla catback
Meziere electric WP
Turn One power steering pump

Insignificant mods
Racetronix 255lph fuel pump/relay kit
Big three wiring upgrade
145A alternator
UMI SFCs
BMR trans-crossmember torque arm

I don't want to rain on your parade or anything, but those numbers sound a little high for your build. It really doesn't matter what the dyno says though, as i'm sure it will run like a raped ape!!

I want to enjoy the car for a little while before strapping on drag radials and destroying that poor little 10-bolt, haha. But I'm with you...maybe I should just get a 9-inch and 3.73s and be done with it.

Exact same mods I'm going to have but I will have a 6.0L Iron Block Mamo ported FAST 102 in the mail as we speak. Got a FAST 102 TB. with the same injectors as you. I didnt get the electric WP just the standard and also used standard rockers with trunion upgrade. But my car will not have AC. Also similar cam 229/234. I will have a one piece aluminum driveshaft, lightweight aluminum flywheel and 25% SLP underdrive pulley as well. Also 1 7/8" Kooks headers with 3" collectors to a dual 3" xpipe and exhaust. Hoping to make over 500whp with my setup.....I will have 3.43 gears and 11.5:1 CR (what we requested) from the CNCd heads with stock head gasket.

I cant believe how high of rpm it keeps pulling with a cam that size, My car makes about identical power to this one up until about 5000 and starts losing power at 6100rpm, this thing is still gaining at 6700 where he let off
