Not a thing wrong with LS7 lifters.

RT

 

Ls7s are good.

 

I stumbled upon those and some morels. I'm going to look into those short travel comp lifters when I get a chance.

 

I run Johnson SLR lifters, I hit 7300 a couple times last year but it seen 7000 alllll summer long.
so far so good
we will see how they like 7500 this summer

 

Going with Johnson SLRs this time - I've eaten 2 LS7 lifters - I have no luck with them. We'll see how these work out.

 

I had an LS7 lifter fail with less than 3k miles on an NA under 500hp 6.0, big cam, good pushrods and dual springs. Lifter failed and pushrod forced it's way into the face. I've seen a lot of similar stories, mine were genuine GMPP LS7s. I have also seen many set-ups run forever with LS7 lifters, I just won't chance it again.

FWIW, I switched to the caddy lifters.

 

I think they have their limit. If youre running a very heavy spring with high lift they wont cut it. For extreme RPM I wouldnt run them either.

For 90% of the trucks getting a cam on this website I don't think I would bother looking at anything else. OP, I would think about a different lifter. Johnson makes a quality unit, as Pat mentioned.

 

I'll let you all know how my LS7s hold up with .600 lift on PAC 1219 springs
