Questions about 1986 Camaro : I just bought a 1986 camaro that was swapped from a 2.8 to a carb 355 out of a 77 vette. it has a bad vibration aroun 1500-2500 rpms almost like a dead miss, but its firing on all 8. the timing is right and the carb is adjusted so I am a little lost. the motor is a fresh rebuilld very low miles still break in period. but it idles fine and this only hapens under load (butterflies open) not on the way back down when your relese your foot from the gas. if anyone can help it would be great..

Answers about 86 Camaro : if the motor balanced right it would cause a vibration ..
