    The cam is suppose to turn easy with 2 fingers.

    Make sure you Dump fresh oil over all the cam journals when you put the cam back in.

    I got the cam fixed now, thanks for y'alls help. I went ahead and installed the timing chain. When I put the #1 piston at TDC and the cam at 3 o clock this was the closet I could get the dots on the timing chain. Is this right or is there another problem?

    Whos timing set is that???? I've never seen one so chopped up with keyways!

    If you used a piston stop and have removed your degree wheel for the picture..... and are 1000% positive you have TDC (and not just an eyeball) ... then I'd order a Cloyes timing set

    It's a summit brand double roller timing set the sheet that came with it said the extra keyways were for adjusting the timing from the chain

    Marv D,

    Howards, Comp Cams, Elgin, SA Gear, and Cloyes all make 9 keyway timing sets that I know of, and probably others.

    Your wrong. Errrr.

    Get the #6 cyl to TDC on the comp stroke so the timing tab is at 0 and the dist rotor is pointing to #6 plug wire.
    You can achieve this by fingering the #6 spark plug hole and turning the engine until a blast of air passes through
    your finger.

    The crank dot should then be at 12:00, so then turn the cam dot to 6:00 by hand, then slip the chain on.
    It should be dead nuts on. When both dots are 12:00 is when #1 is at TDC. I find it easier to see when they
    both face each other.

    If you roll the crank slightly CCW you may find those dots line up perfectly. Hard to tell from the picture, but the direction they're off looks like proper alignment (exactly dot-to-dot) but then the crank got turned slightly CW.

    Did you fix the cam binding issue??

    Guess I've been using the Cloyes 3100A Hex-adjust and Jessel belt drives to long. Never ran across one.

    Like mentioned,, it's jut a few degrees from TDC is most likely the difference your seeing in dots aligning

    And as mentioned,, #1 and #6 come to TDC at exactly the same time. Dot to Dot like this is FIRING #6,, not #1. But no consequence,, roll the crank 180 ° (both dots @ 12 O'clock and your TDC firing #1)

    Yeah I took it out and put it back in and it's fine, not sure what the issue was. The lifters still stay up on their own when I spin it but I think that it's because there is nothing on them.
