My LS1 is officially blown

[streetk14]

After a 6 month ordeal to get the correct parts from a few different companies, my '67 is alive again and I'm quite happy about that. I still have a few problems to work out, but it's on the road and fun to drive.

Here's some info on the engine combo:

2002 LS1 motor
Mp122 intercooled Magnacharger
60 lb. injectors
Holley 90mm throttle body
Patriot Performance stage 2 CNC ported heads w/ 72cc combustion chambers & 2.02"/1.60" valves
Comp Cams XER 224/230 114lsa .590" lift
Comp Cams Hi-tech pushrods
double roller timing chain
Stainless Works 1 3/4" long tube headers

I still need to work on a belt slip problem I'm having. I'm only seeing about 6 psi right now, and I know my pulley combination should be good for more than that. I also am seeing a drop in boost at higher rpms, which is especially bad in 1st gear when the rpm increase in very quick. I have a new solid belt tensioner bracket on the way from Street & Performance that is supposed to cure this problem. I guess I'll see if that's the case next week.

No power numbers yet, but the car is supposed to go to Magnuson for some dyno time. With the belt gripping properly, I'm hoping for 550 rwhp or so. I'll be sure to keep you guys updated.
