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.
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.
pn#88958689 check out pace performance.
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
You should have LS7's already Zach. Caddies are the only thing nicer that's GM.
woke up in the morning,jacked the truck up at a angle front end up...cause i noticed a coolant leak...so i turned on the truck and man it sounded real bad so i shut off quick...i mest it up myself by just jacking it up right away and not turning it on while it was leveled on the ground....so i put it down leveled and noise wasnt as loud but its there and annoying!!
need some recomendations from those who have upgraded theres..my engine os a ly6 6.0 with the oem l92s u think there the ls7 lifters?
going to upload vid....
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.
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.
