i've searched and searched but havent found much info about LS7 Lifters except their a cheap and good.
would anybody recommend them? or would you prefer any other lifter instead? has anybody had any problems with the LS7 lifters?

i have ls7 lifters myself. they are great and i would recommend these. i think the caddy's are a little better, but a little pricey.

They are an OE replacement for the LS1 engines. No upgrades or anything, just packaged in a set of 16 by GM which saves you money. We run them in many of the cars we build. They are not bad lifter for the average street car.

so LS7 lifters are identical to LS1 lifters?

Not identical from what i know, but a stock replacement. You can't buy LS1 lifters anymore, GM replaced them with the LS7 lifter.

I run them.
They hold up well (so far) to an XFI lobe & comp 921's.

Casting number on case is same, internals are identical. GM superceded a couple old part numbers and you can buy them individually now, but for about $60 each. OR, buy them in a set of 16 from us for $119. They are a standard GM lifter that'll work in an LS1, LT1, older SBC, V6 cars, etc. They are not an upgrade perse, unless your existing lifters are worn out and need replaced!

ok for a daily driver/weekend warrior car?

Depends on which springs/camshaft you run.

See sig.
I drive the car more than I should.
I've probably put 10k on them easy.

no problems from the set that i'm running... i am not too easy on my car, either!!! i did have 1 lifter that i had noticed that was cracked when i bought them new. i just took it back to the dealer and they gave me a new one...

good luck

how would they compare to "Comp R" lifters? or the caddy lifters?

BYE RICE

-Caddy racing lifters are an upgrade to LS7's.
-I replaced a set of Comp R's that I had some issues with.
Comp R's are tricky to set up.


These are my cam specs..236/242 .615”/.612” 111LSA
Like I said.XFI lobes..Which are faster than XE-Rs but not as aggressive as LSK's..LSk's require solid roller...Comp said solids should be run with XFI's also,but somehow LS7s seem to be doing OK.

Come again? Who told you that? MANY run the LSK/XFI/XeR lobes on hydraulic lifters every day. It's not a big deal really.

Comp said that in the application guide in their catalog...

I run the factory lifters on my comp LSL lobed cam and they have worked perfect *knock on wood*

I just looked on their latest online catalog. The XFI's are now listed as 'hydraulic roller'.
I don't even see LSK's listed anymore.
Trust me..I agonized over lifter choice when I was putting this combo together 2 years ago.
I distinctly remember seeing 'XFI/solid roller' in print.
Maybe they assumed that when they engineered those profiles,that they assumed that a hydraulic roller wasn't up to the challenge & that they we erring on the side of caution
I dunno..I just remember sweating it a little..But your shop(amogst other ppl) told me not to worry.
You were right..What can I say?
