ok so i have my motor sounding like a Diesel at idle...i need some badass lifters that will handle high rpms..i have been looking at the Morel hydraulic lifters but does anyone know if they would require different pushrod size?
also heard about the ls7 and ls9 lifters?anyone run them,would hate to put them since there oem and they go out again.
so you 700hp+guys what are you running?
If it sounds like a diesel then somethings wrong.lol. wondering the same think cuz mines ticking pretty bad.
4.8, TSP 220, 6L90 swap, 3400 Stall, 4.10s w/30" drag radial and T76 @ 16lbs.
Best ET 11.54@114 w 1.52 60ft
Raceweight 4905 lbs.
If I remember correctly the NNBS trucks come with LS7 lifters from the factory. You will prolly want something a little better although I am sure plenty of guys doing junkyard builds are running the LS7's on high powered trucks. I know I will be tossing in LS7 lifters when I get around to a cam/motor swap this summer.

Use the caddie lifters. Designed by GM and factory rated for 8000rpm.

Ive seen 7600 rpms at 16psi with Ls7s. Youre motor should have Ls7s in them now and they are plenty for what you have.
what makes you think its a lifter
2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
2002 Silverado - 427Lsx w/ Twin gt4202s
2010 Silverado crewcab Z71 - 5.3litre w/ procharger
2000 Wrangler - 5.3litre with some stance
2014 Xsport- 3.5 Eco boost
412 Motorsports
it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
You should have LS7's already Zach. Caddies are the only thing nicer that's GM.

I have morel lifters in my lsx. Work well, but I do have much larger than stock push rods too. I run the caddy lifters mentioned earlier in all my other builds. U should have the ls7 style lifters now, or dod ones. If u have ls7s I bet the sound is not from the lifters...I've turned my ls7 style lifters to 7800 with no issue several times. As long as u don't have the dod lifters u should be ok, if u do. They suck, I trashed several sets of those before realizing they are trash.

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
hear check it out,i messed up by jacking up right away in the am,as the oil was all down in pan of course.
I really hope that is a lifter.
Doesn't sound like that to me.
Best case can be a Twisted/bended roller rocker.
