Finding TDC for straight up timing chain install.help
I'm installing a straight up timing chain in my otherwise stock '77 460.
I pulled all rad, etc off and with a socket on the crank bolt rotated till the balancer was at zero and the rotor was pointing at cyl #1 on ditributor.
I pulled timing cover but the crank and cam were not exactly lined at 6 & 12 oclock so I adjusted by rotating the crank slightly to make them line up perfect.
So I pulled the crank and cam gears off and went to instal my "straight up cloyes one, the cam sprocket lines up perfect at 6 ocklock still, but my stock crank gear had the keyway just slighty ( inbetween the 12ocklock mark and the next tooth towards 1 ocklock, but my cloyes crank gear has the keyway directly in line with the "0" 12 o'clock mark, so my question(finally) is, with the timing chain off is it ok to turn the crank back, counterclockwise slightly to line the wood ruff key to 12 ocklock, because right now it is sitting at say 12:10 because the stock keyway was slightly off???
Second question, I've noticed my rotor is actually pointing just past (left of) the #1cyl mark on distributor, directly in the middle of the #1 cyl terminal and the #5cyl am I at tDC?
Can I tell if I pull my passenger valve cover????
Or is this just like that because of the stock '77, retaded timing chain I'm switching out.
Thanks alot in advance, sorry about long post
if I could give you beers in advance over the net I would.
