Default ls7 lifters questions inside
Will ls7 lifters work in an ls1 and are they better than stock ls1 lifters? How do they compare? I have heard the caddy lifter are pretty good which are better?

From what I have found the LS7 will work in a ls1. The LS7 are rated for a higher RPM. while the Caddy's are even higher (can't remember the RPMs off the top of my head)

Default LS7 lifter = LS1 Lifter replacement
The LS7 lifter is the factory replacement for the LS1/6 part.

What type of preload is recommended? Wild shot here, would they work in an early 90's SBC?

Nope. But when I did lifters I did a full H/C swap, so all around valvetrain noise had a slight increase.
