I was told to use the api cj-5 rotella it is suposed to be the high zinc. I Dont know for sure, I'll call their customer service next week, they have an excellent tech line

im asking about solid lifters with the oil hole in the bottom as I did read in the big banger forum that the cams do wear when you regrind them mainly because of not enough zinc in the oil if you want to change the subject to oils at least let me start a thread lol

[THEFERMANATOR]

All I have read is debate over the hole in the lifter facing helping or hurting. COMP CAMS makes a lifter design that gets more oil to the lifter without drilling the hole in the lifter face. it has a groove cut in the side to channel oil down from the galley to the lifter. This way you keep a solid face, but the channel will dump oil down.

I would use rollers if you can find me a cam to suit

[smokeonthewater]

I think pretty much any cam will work w rollers..... just can't use a roller specific cam w non roller lifters...

Aren't you having a cam reground... could you not specify that it be a roller cam?

Don't work that way. Roller cams have a COMPLETELY different grind profile to them than a flat tappet cam has. The contours of a flat tappet cam with roller lifters wouldn't last long, not to mention roller cams are made of billet steel whereas flat tappets are cast. I'm sure Aussie could get a custom grind done, but it would cost ALOT of money to do so. I know COMP has blanks that can be custom ground to most anything, but the cost would be up close to a grand US probably for a one off like a 3.7L.
