    Just make sure when you pick a cam that you understand where it will make power, and to plan your valvetrain components appropriately. The higher it revs, the better the components you'll want to have in the top end of the motor: springs, keepers, locks, rockers, pushrods, timing gear, etc.

    Probably just the GM LT4 hotcam kit then. It's a fairly mild cam in the grand scheme, but will provide nice gains with a good tune and supporting bolt ons.

    I'm looking for optimal power though. I will have lt1 edit along with lc1 when I purchase the cam so it will get tuned. I also plan to purchase new springs and guides and locks as well as push rods. Is there a max an lt head can handle on lift?

    Every motor has a limit on valve lift, but you're not going to get anywhere close with a hotcam or any other streetable cam.

    with the tpi style engines the rocker studs were pressed in and it wasnt recommended to go over .475 lift.. different concept here?

    A hotcam or similar can utilize stock studs. Any cam that will work well with stock heads most likely isnt going to have enough lift to worry about it. But if you wanted to run guideplates then you'd be getting screw in studs anyway.

    Dont know, I'm not familiar with that cam. It does seem to be a fairly large cam though for an LT1 with stock heads.
