ID this lifter

Any idea what lifter this is? Was told Chevrolet Performance. Set of 16 came with a slightly used spring kit. Thanks!

Based on the oil hole on the side and the retainer those aren't Chevrolet Performance brand lifters. Looks like they have quite a few miles on them too, or were installed dirty.

Decent lifters are less than $200 dollars for a set and the amount of catastrophic damage they can cause your engine is enormous. Get some new lifters. I had a stock LS1 lifter decide to die on me and took out my entire engine. I wasn't even racing, just out for a cruise to a local brewery.

Summit sure is proud of their lifters if you can wait a month. Seems like a good deal.

Or you can have a set off ebay by thursday if you want to roll the dice with "GM LS7 lifters bulk packaged comes in plain box",
There are some on ebay right now with real GM boxes, sets of 8 for $99, but all their negative feedback is about these lifters.

I'd buy from a trusted source and cross your fingers.

Having said that about new lifters, I don't think it's a good idea to install used ones. Maybe if you bought them originally and knew they were real GM parts and they had low mileage. Otherwise no.

For $200, I probably should just buy a set of Morel 6504’s.

Any operational differences between these and LS7 lifters?

I was talking today to a guy on facebook who seems to know his stuff and he uses Johnson or Morel and avoids the LS7 lifters for serious builds. He's run both the Johnson and Morel to 8500 rpm.
