PROJECT LT-GUN

The car sat for almost 2 years without a motor, transmission or a windshield so rain, rats and dust destroyed everything. So I cleaned and painted for a few months and now I can get started on the drive train

So now for the engine I start with a 1994 Chevy iron head LT-1 10:1 comp

Ported and polished the heads and put 2.02 and 1.60 valves in it I put about 30hours in the port work

For the cam and valvetrain I went with a comp XR269HR-12 108 center line 112 lobe sep 218 and 224 @.05 duration lift .495 .503 but it will be much grater since I?m using 1.6 roller rockers. For the spring I used come 325lb SBC

Intake using port matched factory lt1 manifold with 30lb injectors and a twin 58mm throttle body
