Big block pil pump on small block Chevy
I'm freshening up my 400SB Chevy with new rings and installing a set of used Vortec heads. Just for insurance, I am going to discard the old oil pump and install a new one. Here's my question...can I install a BB oil pump? If so, do I need a different length intermediate shaft? I like the idea of the big block pump having more gear teeth and producing slightly more oil volume without being much harder to turn than the small block pump....Do you gents agree?
