I have a 94 LT1. It has a LT1 Hot Cam, ported heads, ported intake and car is stalling. Just replaced optispark and injectors. When I excelerate it bogs and the brakes have no pressure (brakes been bleedend). At high RPM's it sounds good, but the car doesn't run correctly. Would anyone be able to tell me what the problem may be.

P.S. I checked intake and it's not leaking.

 

Have you looked for a restriction in the intake tract. A friends car was having similar problems once and I took the cover of the air filter and a mouse had built a nest in the air box . I gave him he!! for a week over that one.
