Id run the LS7 lifters out of the Comp and them. The LS7 are made for high RPMs and there cheaper than the Morels. But if I ever have to have lifters Im going to more than likely run Morels but the LS7 are cheaper and I definately will keep them in mind esp since I dont have a lot of money.

The Caddy lifters work great for me. Just a note, I work at a Chevy Dealer in service and when looking up the part number for the LS7 lifter, its the same part number for the 2006 up 4.8,5.3, and 6.0.

Personally, if u have the money get morels. If I had to use anthing else I would stick with stock gm lifters for below.640 lift and 7k rpms. If it is a race engine morels are a must.

The stock replacement lifters tend to go bad. I would spend the extra money and go with the Comp "R" lifters. I have used these in 3 other motors besides my own and never had a problem. I shift mine at 6800.

Hands down Morels are the best hyd. lifters on the market. The main downfall is the price, they are almost double the price of all the others. Most of the OEM style lifters (comp, crane, melling, LS7, caddy racing) are usually good up to 7000 rpms. After 7000 I would highly recommend going to something like the Morel.
