    LS1 to LS6 top end conversion: What Cam?

    I currently have an LS1 block with ported complete LS6 heads, a F.A.S.T. intake manifold with the F.A.S.T. throttle body, and am currently looking at various cams to bring out good power for street usage (not some of these more aggressive race camshafts, yet). I want that noticeable loopey idle that I am sure we are all after that makes some GOOD power, and I am more than willing on upgrading the necessary valvetrain components in doing so. I looked at some cams with duration in the 230s, LSA 112 or so, but the lift was only .525/.525 and was thinking that the good lift here would be between .550 and .600. I know that duration is the important factor here, what should I be looking at? Thanks for any help you can give me!

    you don't need cams in the 230 range to make good power for street usage.

    i would suggest the vinci XXX, 055 or 056 cam

    thunder racing has a few good ones to consider as well

    the 224/224 is a popular one, but i would suggest the 224/227
