I did try Redline 0-5 once also, it was faster than RP, but my particular engine smoked with it.
I know a bunch of guys preach the Joe Gibbs, but, I also know some of them supposedly said that their lifters wont pump up with it. True or False?

What's your opinions?

I didn't read through all the replies.. I have used Lucas 20 race oil for bracket mode for years in mine and Randall's truck also... heads up/class I used Lucas 0 and have had very good results....
as far as pumping up lifters a stocker shouldn't have had a lifter that pumps up for a VERY long time..

How about when you have Sherman or Smith "hydraulic" roller lifters? Can thinner oils be counterproductive?

All I can tell you is back when we had hydraulics in the LT1 car we were using Lucas 10-30 full synthetic race oil. Decided to try RP 5-30 and twice a couple rockers came loose. Went back to the Lucas 10-30 problem went away.
