    Hey guys, we just tore the camaros front of the engine apart.

    We put the #1 piston at TDC (the distributer also was at the #1 spot) and we tore it apart.

    When we got down to the cam (gear) we saw that the little cam mark was 180 degrees out (it was pointing straight up, instead of down)

    Can the car run with the cam 180 degrees out? Also, could the distributer AND the cam be 180 degrees out? Or could the distributer be 180 degrees out, and we are on the wrong stroke? (it did blow our fingers out when putting it to TDC)

    Im not sure if it matters, but the cam in there is this one: http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=2409&prmenbr=361

    (The 280H one, so it acually has .480 lift, and not .490 lift) - Although we could of read the numbers wrong.

    Thanks for any help!

    350

    EDIT** well, we were told it was a 327 bore/stroke out to a 350

    The engine was from a 67' impala ss (from what we were told)

    Yes, that's fine, turn the crank another 360*, you'll see the cam only tuns 180*, with the timing marks now pointing at one another.

    So from your description it's fine, compression when the distributer would be firing #1 cylinder.

    Some people install the cam with the mark straight up, some install it with the mark straight down, both are correct.

    sorry for not posting this earlier, but i figured it out.

    They are lined up when #6 piston is at TDC, and not #1 piston. (when i say lined up, i mean dot to dot) I heard that chevy is the only manufacture that does this, everybody else puts #1 at TDC when they are dot to dot.

    You can have the cam @ 12 o' clock at TDC on #1, and the cam @ 6 o' clock at TDC on #1.

    It's different due to the lobes for intake and exhaust.
