OK I have a 350 small block in my rod now out of a '79 truck. I'm trying to save some space between the radiator and motor. I would like to know I can change the harmonic balancer to a smaller one that I have off a 283 small block. The balancer on the 283 is about a 1/4 of the size in thickness. I've gotten two opinions on it and was told it will work because the motor is internally balanced. Has anyone done this or know if it will work? The 283 motor is from a 70's, maybe like 60's nova.
