Never seen a flow sheet on the LT5 heads before only heard one rough figure before. At some point this year Ill be making a fixture for one and flowing a stock one just to see, maybe some work will follow, see how things go.

Re: (reground) cam went flat?
 

There is a difference between the 90-92 lifters and the 93+. Do not remember exactly what but I think the new ones are slightly higher and to use them in an earlier engine Geoff cut the valves down .001. You can use the older lifters in a later engine but using the later in a earlier engine may cause sealing problems.

PS Acording to what I know about spring pressures the LT 5 should be ok without the additive. If you use Red Line it still has the older additive package.

Re: (reground) cam went flat?
 

Lifters are the same, the valve length is longer in the 93+ motors.

Really? Good to know. Wouldja happen to know the API rating?? Rotella T has the good stuff in it as well, but it is actually a Diesel motor oil, and has (I'm told) more detergent in it - perhaps more than necessary to be used in a gas engine, as a rule. Having said that, Comp Cams listed the Rotella as one of the oils recommended as a break-in lube for a new flat tappet cam (along with their break-in additive).

Dayam! I'm not a chemist, and lubrication is a complicated topic. Make a mistake, and it becomes $$$ very quickly! It is hard to pick out the truth from all the hype the oil companies use without a good understanding of the chemistry involved. So, for now I'll go with Marc's recommendation for the Z (AMO 10W-40). The science he used to make that determination makes far more sense that trying to sift thru the oil BS w/o the right tools to assess the distinctions between them. I don't know 'bout you, but of all the products I buy, I'm hard pressed to think of any product that is surrounded with more advertising hype and pure BS than automotive oils...:mad:

Whatever oil Marc H. says to use, is good as gold for me.

Re: (reground) cam went flat?
 

I don't know if i mentioned it on here before or not, but i went to a seminar last Sept. put on by Joe Gibbs Driven oil & hosted by Lake Speed Jr. was very, very good. even before the seminar we were using J.G. BR/XP-4 (same thing). only thing we could get some flat tappet stuff to live on, during break in. helps not only cams but ring seal a bunch too. i'm not getting into great detail...don't have time, sorry. quickly...as for API ratings & whatnot, since Joe Gibbs oil is not on the retail market, (never will be acording to them), Wal-Mart etc. they don't have to adhere to government standards (for emisions, detergents etc.) so they can build the oil how they want too. as for Rottella T. yes it's diesel oil but what it has is more Zinc & Moly, that's the key to that stuff. the government ratings for diesel oil changed a few years ago & i think it's set to change again in 2010, getting worse each time. by the next change, 2010, there won't be really any benifits to using it any more:dontknow:. could go on & on & on...gotta go. hope this helps some of you...a little.
