Cliff,
I have a 1986 Pontiac Firebird w/a LG4. I put on a Edelbrock Intake, and a set of headers, along with a single 3" exhaust (w/ Holley crossflow muffler), AND replaced the OEM cam (179 @.050s) with a COMP CAM 260H (212@.050s), also with a 50K volt coil with a plug gapp off .055s. I am looking to rebuild the CCC carb. I was looking at your HP kit, and I wanted to know what rod and jet sizes would you recommend to get for this car.
