Well two months ago a lifter pin came out and dystroyed my LS-1 block along with my camshaft, i need something new. Nick Williams did my cam install and tuning before on my LS-1. So after much talking Nick i decide to go with a new 402 LS-2. The short block came from SDPC i chose to go with the Callies crank and rods. Nick and his crew put the whole thing together and did all the tuning. Haven't got to have much fun with it yet, just pick it up last night and traffic was backed up on the interstate last night driving back to Greenville, though i did lay into it a few times and i couldnt be more happy. And to day rain so cant really see what it can do just yet, and it is Thanksgiving. Much thanks to Nick, Bob and the rest of his crew at Williams Performance. Thanks again.
The rest of the mods:
AFR 225's
Comp Cams custom: 244/248 .618/.618 112LSA
LS-7 lifters
America Racing 1 7/8 headers with their catted y-pipe
Fast 90 intake
NW 90TB
Textalia 0Z700 clutch
Racetronix fuel system
42# Delphi injectors
Melling high pressure oil pump
25% underdrive pully
And now the Dyno Results:
527 hp and 495 tq SAE
Hp peaking about 6100
will post dyno grap if i can get someone to scan it

Are those cam numbers exact? XER lobe should have a .612/.615 lift at those durations. Is the cam a 112 LSA w/o any advance and installed straight up?

I'm pretty sure those are the actual measured results of the cam, not the advertised dimensions.

For all those wanting to know the C/R i called Nick and he said it was 11:1. And sorry i posted the wrong lift numbers i didnt have the cam card at the time and i didnt want to bother Nick over thanksgiving. The actual lift numbers right off the card are .612/.615. Thanks for the responces, oh and i would have a vid of me pulling the Z06 but someone accidently turned off the camra at the start of the race.

Is there any advance ground into the cam and was it installed dot to dot or degreed? what degree advance if it was degreed?
Nasty graph...looks like a stock curve only climbs much higher. I could not ask for more if I get close to those numbers with my set-up.
