Re: Harmonic Balancer

No one knows of a great balancer for a 383? Or maybe shoot me the right direction. The setup is HSR,xfi292,AFR210, and the above link of course. I guess it does'nt have to be ATI but it needs to be under 7.5in for it to work with my timing cover, and under $500 would be cool.

Re: Harmonic Balancer

Go to summit's web site and in the search box type in harmonic balancer. Then use the drill down menu on the left side. What you want is an internal balance unit that is neutral or "0" balance. With that rotating assembly you will also need a neutral or "0" balance flywheel or flexplate. The factory flywheel/flexplates have a weight on them even though the factory motors are internal balance. (except 400 cid)
