chevy 283

I have a chevy 283 that i can not find a harmonic balancer for can any one HELP me ive looked every were and can only find one for internaly ballaced engines. I do know the OEM part # is 3896904

What exactly is the difference between internal and external balance. I would assume that an internal balance engine has symmetrically weighted flywheels and balancers? The 302 in my sister's 83 mustange is externally balanced because the flywheel has a counterweight on it?

That all interesting but still dont tell me were i can find the correct one the one i found says it will fit 283 302 307 327 & 350 is this correct?

YES I SEEN THE POST BUT ALL THE PARTS HOUSES SAY THAT THERE UNIVERSAL FOR THE 283 302 307 327 an 350 he said only the 283 will work SO IF THIS IS THE FACT HIS POST DOESNT HELP IF I HAVE TO HAVE ONE FOR A 283 and all i can find is universal how will it work?????????????????????

Get one cheap from a parts house that is good about returns, install it, and if the engine runs rough, return it and look for a 283 specific balancer.

Classic Industries has a balancer that fits 55-67 265 and 283's and 68 307's. Only $162.63, ouch. They also have balancers that fit everything but 400's for 69.95 from Proform which isn't GM, but is a licensed GM manufactuer.

Thank You thats what i was wanting to know 162 is not bad price think ill go that way i aperciate all your help
