Cam Question...
What is the maximum lift that stock heads on a 99 LS1 can handle? I bought a comp cam xr275hr-12 and have it installed...but I'm nervous about the stock valve train. The lift is .566 intake and .568 exhaust...and 222 duration.
Can anyone help me out?
Thanks

Yea if your buddy is saying that, then I wouldn't listen to him for anything about your car..lol. I have a 228r cam which is considered "SMALL" compared to other cams, and the lift is .588/.588 on it. I've seen people run huge cams or even custom ones with lifts up to like .635/.640 on stock heads fine. The big cams like trex,ms4,polluter, tsp giant, are all over .620's easy and people daily drive those cams with stock setups even.
