do i need to restrict oil to lifters with roller cam

mopar3762 said

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

Cooooorect!!!!!!

Some modern roller cams no longer require a bronze gear and restricted oil passages, know what you have, call the grinder!

If you need to restrict the oil galley and use a bronze gear, this procedure is out lined in the MoPar engines book for small blocks.

You'll drill the oil passage to size and hammer in a tube that you pean each lifter bore with a peening tool.

Otherwise, you'll need to bush each lifter bore, which is a great way of doing things. But expensive. I would also add to the list of things to do on this mod a check of each lifter bore and straighten as needed.

Very expensive when it gets added up. But worth it!
