What pushrods do I run with LS7 lifters

If you are asking about pushrod length, the standard procedure is to take measurements using an adjustable (measurement) pushrod. What components are you changing?

LS7 lifters are a factory replacement, you should be able to run the same length as you would if you kept the stock ls1 lifters.

I went from a 7.4 to a 7.350 after I installed LS7 lifters, but they are all different depending on cam.

I have an ms4 cam I changed to the 675. lift springs from texas speed and i'm running stock rockers. I didn't mill the heads or deck surface so that is the stock deck height.

Typically we will have to go with a little shorter pushrod with those lifters but like mentioned earlier I would definately measure it out to be sure. You can get the comp pushrod length checkers for $20, saves a lot of guessing and headaches in my opinion.

Factory replacement, yes...but they do have a bit higher cup height than the older LS1/2 lifters, so they require a different length pushrod.
