I'm going to have to get another harmonic balancer, I been using a 6 3/4 in. balancer on my sbc internally balanced. The outer ring is moving towards the timing cover. I don't know if this has anything to do with but I did put on a new flex plate when I changed over to a 700r4. Any how I read that a 8 in. balancer wasn't really needed,it just added more weight to the crank. The 6 3/4 was bought new but it was a cheap one only about 70.00. But now I'm thinking I might be better off with an 8 in. as this engine does see 6 grand some times but not alot. When walking around the junk yard I see 6 3/4 balancers on V6 engines, all V8's have 8 in. I like the idea of having less weight on the crank but maybe an 8 in. would be a better choose. Please inlighten me. And yes I know that a Rattler is the best but I didn't want to spend 300.00 plus for a balance.
