Oil restrictors for Small Block Chevy
Posted: Mon Oct 13, 2014 10:43 pm
My son and I are putting together a 377 Small Block Chevy for drag racing and limited street use (it's 10 miles to the drag strip from my son's house). It's a relatively high rpm motor (cam peaks at 7800 rpm). Solid roller Comp cam, SS roller rockers, 400 block, AFR alum. heads, COLA 4340 crank, Lunati rods, Manley pistons @ 13:1 compression. We are thinking of using oil restrictors in the oil galleys (the block came with them), but I have heard conflicting info on whether or not to use them, drill them out, leave o-rings off, etc... What experiences or recommendations do you guys have with them?
