Can an early 421 sd crank work in a 70 455 block using an aftermarket SFI balancer and 70 timing cover. I have heard these are a short snout and can have issues with balancers. Thanks

Thanks Tom, just trying to avoid any major problems mixing parts. I'm not real familiar with early 60's Pontiac SD parts and what they will or will not work with. Anything else I need to know before building a 440 using this crank? Thanks again
