With a big block and Indy SR heads the SRs are external oiling and being fed from the rear by the oil pressure ports. I know the sb only has the 1 rear port but u should be able to run a Y block to feed the heads. Or sm I way iff base here. Kim
That’s where I’m heading at this point. But rather than have external lines, I’m thinking of drilling into the gallery that feeds the oil pressure gauge and using that to feed the rockers through the original passage in the block.
I just need to make the time to go out there and look at it real close and think it all the way through before I start drilling holes. As I see it now, the oil going to the gauge port isn’t taking oil directly off the oil gallery feeding the mains.
I really need to go do some work on that but I’ve got other things keeping me much more busy than I want to be.
