I run a 416 LS3, but I chose to use the 8000RPM Caddy racing lifters. I've heard nothing but good, and so far after many runs at the track, and daily driving, I havent had one problem. Many with big builds use Caddy or LS7's

well most peopledont rev past 7-7500 rpm.... that said, the ls7 lifters are very good pieces and are half the price as the caddy lifters. i was even able to get some from texas speed on sale not too long ago 4 only 119.00 bucks. comp also makes a very nice one i think the model is 875 (875-16) cant remember really. good luck with everything

Morel goes into our race engines, anything else is just stock and is not a true hi performance lifter. Application also comes into play... cam and springs should play a major factor in the decision. Caddy lifters have been the wrong choice for many many people and an LS7 lifter is just a stock gm lifter. We've seen them need to be replaced at 14k miles (develop a tick).
Aplication application !! what rpm is the car going to see all the time and what springs and cam profile??

Well i will be running a magic stick 3 cam with prc dual valve springs and 7.4 push rods. Depending on where the hp starts to drop off on the dyno will depend on what rpm i will be shifting at but i am guessing high 6k rpm shifts. I wil be putting in katech rod bolts also!!!

I could not put it better myself. I have an Ed Curtis Cam that is as big as the MS3, Ed's cams have way more aggresive lobes than anything i have ever tried with a 614 lift. I have had no problems. I have stock lifters with comp 921 springs ti retainers, 243 heads, and the GM ZO6 valves.
even the Morel will have issue in an improper setup.. it will take longer to destroy but nothing can compensate for a poor setup.

DD with Pac 1518s on XFI/XE-R lobes what would you recommend for lifters? Will probably never see the up side of 6500. I planned on using new Eaton ls1/ls6 stock lifters.
