383 sbc
Have a 383 with balanced eagle assembly...it has a auto flexplate on it balanced and sfi...the front balancer is a stock 400 sbc balanced to flywheel I'm assuming...I want to replace this balancer and use a sfi balancer..question?? does it have to be rebalanced to flex plate?? I have a fairly new 350 sfi fluid balancer..was told it might work but not sure enough??
help needed
thanks
