ls7 lifters ques...
im gonna be putting my engine back together pretty soon.... IM gonna be running ls7 lifters/ I'ver been reading that, these lifters require a shorter pushrod? is that right?
or will my 7.4 be fine?
any-b has done this swap before, what size of pushrod , are you all using?

Im in the same boat as you. I am just going to get the pushrod checking tool to get the actual distant then add the preload and have them made. Even if some guys have used a set length it can be wrong for your motor.

The LS7s are reportedly .050 taller than the older style lifter. I don't know when they stopped using the older style lifter though. I just did a H/C swap and I am now using 7.300 PRs. I dropped my head gasket thickness by .010 and installed the LS7s. 7.300 got me .050 preload.
