Looking for wisdom on buying balancers for SCJ, but for two different applications. For one car we need a stock, correct replacement C8AE-C. The second is for a T-bolt clone my dad brought home, sporting an FE that I'm guessing was built in the 80's (more on that). He just wants to run it for fun, but I'm thinking better than stock should be applied in an effort to not ruin some rare parts; there's an SCJ balancer out front looking suspect. I appreciate any feedback.
FE of the 80's - we can see an SCJ balancer, 406 heads, Ford adj. rockers, an Edelbrock F-427 intake and a Holley 750. Haven't checked cam yet, but it sounds big. Seller didn't build it but said the heads had bigger valves and it had really high compression. I'd like to swap an intake immediately but haven't convinced him there's far better choices.
