Anyone using 3/8 Pushrods?
Figured this was a good place to ask with all the high hp FI builds. Anyone using 3/8 pushrods and did you have to clearance at all?

Depends on the heads. 11/32 is a good option on most GM castings other then LS7. Aftermarket castings will often accept a 3/8".

Thanks guys... I'll check what length I need and then grab a set. I hope with the geometry of the Crower rockers that they won't have any clearance issues. It sounds like I should be good though.
