Default 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.

I'd use an 11/32" for those.

Mast Heads with 3/8" .120" wall Intake and 7/16" .165" exhaust..
Previous setup was LSA heads with 3/8" .120" Intake and Exhaust though, cleared just fine.
