Title: Harmonic balancer questions
Post by: john a on September 04, 2017, 02:24:36 PM: My old original balancer came apart this weekend, it only lasted 53 years. The v belt groove is the outer ring of the balancer. Looking at new performance balancers the pulley bolts on the front of the balancer and will cause alignment issues with water pump and altinator. Does anyone make a balancer that will aline like the original? If so who's would you recommend? This is a stroked 390 444 ci 6200 rpm street strip deal. If I remember right it's internal balanced.

Thanks, John

I have a romac without pulley and adapted a pulley from
a Volvo B 23 engine

All FE belts are the same spacing from the block. An EDC, 390HP, 406, 427 and a 68+ FE balancer will get the drive pulley off the rubber. Maybe others.
