Was looking at this lifters for my boosted 2005 5.3 build for my camaro. Was wondering if anyone has used these before on a boosted engine and if so, how did they do/hold up. Thanks

I don't know anything about these lifters in particular, but whether the engine is boosted or not doesn't affect the lifter. Cam ramp rates, RPM, cam lift, valve train weight, and spring weight are what affect it. If they hold up in an N/A car, they'll hold up in a boosted car.

Seems that at this point, Johnson or Morel are your best choices since LS7 lifters are out of stock. There was talk that the Lunati's aren't as good as Johnson and Morel.

Lunati is rebranded morel. I have been impressed with Johnson customer service so far but haven't fired the engine up yet. Hopefully it's as good as they make it up to be. 2116 lifters btw. Reduced travel with .093 travel and I set it to 45 thous preload.
