The reason is that 3 different motors I have munched needle bearing lifters. Seat pressure is 350-400 on each. .800+lift. I would like to go to the bushing lifters.
I like the manifold idea, very doable.There was no picture on the link, but I get the idea. It just seems to me that with a Bridgeport, a centering drill, and good measurements, I could pass a 1/4 inch bit right down the middle? The lifters Indy used on this 655 raised cam motor are .904 SBC offset lifters.Really. They have a pressure feed band around them, so oil could me metered into the 1/4 galley with a jet. The trick is would the bit stay true?
If you ever watch Allen Milyard on Youtube, you realize anything is possible.

Really appreciate the replies!
