Cam question...again!

[RUFFNECK]

.....im not 100% sure but i think .600 lift is to high for a stock 5.3

Yeah I think ur right cuz I dont think the stock pistons came with valve relief.

Wow thats Wide separation, but it yields a large power band as well, would like to see some #'s on HP & TQ this cam makes, weird specs.

Even if there is enough piston clearance you'll need some serious valve springs to handle over .600 lift. Like some PRC double springs or somethin.

(LSR cam)it is over .600 lift
but its what comp cams recommended. Im sure they did quite a bit of testing on it. On the cam description, it says for 4.8/5.3L small blocks
