Changed rockers because I've always had problems with ball and cup push rods so I thought I would try ball and ball push rod oiling for a change. I was told by the the engine builder that BSFC lb/hph is what he prefers. The car ran 9.23 @143 before the changes, so it's heading in right direction. My son and Brett Miller have been talking about this build and what he thought it needs and about what the heads and intake need to get this thing to the next level
