the reason he was asking was he stated the hydraulic roller cams throw around a lot of
oil seeing that the holes are rather large in the lifter valley alot of
oil would be thrown into the valley by installing bushings it would keep the
oil in the bottom end. i already have the .090 restrictors and the other oil mods done. this is something that has been done on different race engines.
i talk to different builders and they all have different opinions. gessford oils the top end through the pushrods like a smallblock so i dont know who to believe anymore. i know all builders do things differently and they love to take apart other builders engines to see what they doto learn there secerets.
the builder i am using does are circle track motors, we have back to back championships 06-07 with his engines he makes good power for reasonable money.
