what is the timing on 1991 firebird 305
It used to be a TBI but I took off the TBI and put a Edelbrok intake on it and put the motor in a 79 firebird. so it has no computer to it either. just straight honkin motor

The stock TBI initial timing is 0*. But you can set it to whatever makes your engine idle the best.
