I have a 318 poly with a 727 in a 1966 Satellite. Looking to purchase a 408 stroker 375 horse. If I buy the fully dressed engine will I need a different balancer, flexplate, what else?
Contact Bruce Toth and stick with the Poly. He can build you a big cubic inch Poly with a set of ported heads. Add a factory 2 four barrel carb intake if you like. You will be different and admired by your friends.
Whoever you are buying the engine from should be able to tell you. If it’s an internal or externally balanced engine. I don’t think I’d want to use a 54 year old balancer on a new engine.
