i'm sorry guys i posted it up so fast forgot to put in the correct info its a 350 Chevy, and also i feel embarassed/stupid.... i measured my harmonic balancer earlier today and its 8 inch....
so i kinda answered my own question.... i figured it was 6 inch but obviously my eyes are not as acurate as a tape measure.... none the less this was a very informative discussion
thanks for all the input
Nate
