I think he is talking about the timing gear on the front of the crank, and is saying that he doesn't see a dot on it to line up the cam and crank gears "dot to dot".

Yes 3 keyways what do I do? No dot at 0 on the crankshaft gear heads are off so I can see TDC easily

Do I just put the crank at TDC for 6 and 1 then camshaft dot at 6oclock? this should be tdc for #6 ? then 180degrees is tdc for 1?

Thanks Dave. That's what I was thinking but I have never seen a multi-keyway crankshaft gear with no 0. So I just found my 0 put my Timing Chain Dot at 6 o clock.

0 would be the keyway without a mark in that case. put it on that keyway, install the chain bring it to TDC on #1 or #6, drop lifters into the bores. depending on wheter it's 1 or 6, both lifeters should be all the down and the other two should be up off the base circles but those lifters should at the same height or very close.

If you have a cam card and a degree wheel, it would only take about an hour to find the correct keyway.

Point the crank key directly at the center of #1 cylinder and put the cam dowel at the 3 o'clock position and install the gear set.
