how many RPM's can the STOCK 1997 LT1 hydrualic roller lifters take? another thing i heard only vette lt1's are 4 bolt mains but is it possible that some camaro ones could be 4 bolt. and how many rpms can the comp cams 1:6 pro magnum roller rockers take for RPMs?

 

stock lifters with low miles can see up to 6500 rpm's safely

i dont think that vette LT1's have 4 bolt mains, but the Corvette grand sport LT4's do.

the comp cams 1.6 pro magnum roller rockers assuming they are non self aligning with guideplates, hardened pushrods can see up to 6800- rpms safely with correct prings, and up to 7,000 rpm's with a hydra rev kit,

the magnum self aligning rockers can see up to 6200 rpm's safely, but i wouldnt go much higher for too long, or the rocker fulcrum might jump off the spring cap.

well on that under blocks it says about 2 and 4 bolt mains. i don't have hardend pushrods they are stock, stock springs, and actually i double checked i guess i only have just the comp cams 1:6 magnum roller rockers part # 1416-16 on comp cams. i have my shift points at 6000 1-2 6020 2-3 and 5920 3-4 rev limiter is set at 6300 too. so should i be ok? rest of the valvetrain has 94010 miles on it. oh and what is the crank made out of on the lt1?
