i bought the cam and lifters used from a buddy ,he said he never noticed the issue , then again it was ran in an older block, so not sure how much of a difference there is in the two blocks lifter bore heights .When you think of how much time it actually spends at max lift during the whole rotation of the lobe, looks miniscule.... It looks like it's ran already, any issues?
Yes stock cam journalsDoes this engine have standard diameter cam bearing journals? Regards, Chase
The lifter body on these lifters are shutting off the oil galleyI would not be too excited about running a used cam and lifters in a different block myself.
However, if you are ok with that and if the base circle was OK for the app why not bush the lifter bores?
Definitely would not want to spend the money on a new set of lifters for a used cam with the wrong base circle.
