Top-End Oiling
Has anyone seen an article or post describing modifying the cam's #2 and #4 journals by either grooving the cam journal or adding a lead-in slot to the oiling hole to increase oil flow to the rockers? With a 340 HiVol pump, does this add life to the top end? Does enlarging the oil drainbacks in the heads and block help? Thanks for any help.
