LS7 lifter valve lash

[Still2slow]

Another member(HellTeeOne) and I are knee deep in an Advanced Induction HCI install on his 97 Z. How far past zero lash should LS7 lifters be adjusted( ie 1/4 turn, 1/2 turn, etc)? I'm more familiar with comp R's in LT1 applications. Thanks for the help!

I have used 1/4 turn in the past with great results.

Thanks for the reply. Any issues with chatter at 1/4 turn past zero?

If I remember right I went 1/2 turn.

Nope, like I said, 1/4 TPZL is what I like to use. No problems.

I use 1/4 turn with poly locks zero problems.

I am currently having a disastrous situation with GMPP 1.6 rockers and LS7 lifters trying to get the adjusted correctly.

I have tried everything from 1/4 past to 3 turns past and it makes no difference.

Most of my are set at 1/2 past and seem to be pretty good but there are 3 or 4 that just will not adjust correctly. I dont think its a lifter issue though.

When you say they won't adjust correctly what do you mean? Are you sure you are on the base circle of the cam when adjusting?

Nope, like I said, 1/4 TPZL is what I like to use. No problems.

For future reference I went 1/4 turn and the engine seems happy. The rockers are a little loud on initial cold startup but only for a few seconds until the lifters "pump up", which is typical for roller rockers. Thanks for the help guys!
