that information is well documented, but many guys aren't aware of it! when I had my cams ground I had some inside information from my cyl head machinist who was involved with GM for many years doing RD work for them! kind of like insider trading?

So the GMPP lifters are pretty legit?

Tim I understand and respect that, but I will disagree! I have been running more than .600 lift with them and 6000 RPM in the same engines for 15 years never had any issues. I never bought into that. Now I know many will doubt my experience with these lifters, but they work for me! I can run 5800 rpm for extended runs, and run north of 120mph ( as long as the drives stay together)
guess it's just what I was always told thats all... no biggie.. lol

The way i understood is that the standard gm roller lifter if you went over .578 lift the oil hole in the lifter will come out of the lifter bore and the lifter will lose its prime and clatter..also some will experience oil pressure loss if you have a lower pressure oil pump..

i have a stock Gen 6 sitting on the stand at the moment with nothing in the block but crank and cam. i will pull the spider off lifters and do a little measuring this weekend...

Cole, they will work fine but as mentioned (and it is imperative) that you check the lifter height when it is down on the base circle!!! if it falls lower than the dog bone it will twist and the roller will not be squared to the lobe and all s?it will break loose. Also beware of your lobe accel rates. They are good lifters for mild cams. Do your do diligence! I run more than .600 lift But they are still mild cams in the big picture!

No wild lift here. Thanks!

isky red zones in my engines,seat pressure at 160lbs,cam and lifters look practically brand new after 8yrs of running.I'll snap a couple pics right before I install the intakes on my 088 heads.:D

and I use crane long body lifters in anything over .600" lift.
