What is the part number for these lifters? I'm looking for a plug and play replacement from my stock lifters.

Not sure on the part number but I've been told that you still need to check push rod length. I've also heard they are a direct replacement but for added insurance I would go ahead and check the push rod length just to be sure.

They're stock replacement.....absolutely plug'n'play.

I put a set in my brothers car....pushrod length was unchanged.

They may be direct fit but there is a small difference in cup depth between lt1 OEM lifters and ls7 style lifters.

Had mine checked, still stock length pushrods too.

No, not true anymore.

There were a few reports of them needing different length pushrods when they first came out several years back but this is NO longer the case. Stock PRs work with them just fine.

I'm going to have to disagree here, the LS7 lifters I bought from the dealership within the last year had the SHALLOW cup.
