hello i am building a 408 stroker with competition solid roller cam with comp cams 843-16 lifters with holes for pushrod oiling do i need to restrict the oil in some way for the lifters
a roller lifter uncovers the the oil galley and oil pressure will drop to zilch, first off you need a aluminum bronze distributor drive gear and hardened shaft. yes you need to block off the oil with a roller cam either by bushing the lifter bores,or a lot of drilling and plumbing. to much to get into here, on the drillind procedures. take care
Here is another statement from their Chrysler tech notes:
"Even though COMP Cams® roller lifters will work without oil system or lifter bore modifications, it is highly recommended that on any racing engine the lifter bores be modified. This will ensure that in the case of a pushrod failure and the lifter coming out of the bore, adequate oil pressure will be maintained. The proper procedure for this modification can be found in any of the materials available directly from Chrysler, or any top engine builder can perform this modification."
