I am probably just so frustrated that I am over thinking things but I replaced a set of intake gaskets on a motor and switched from a points style distributor to an HEI at that time so i never bothered to mark the distributor.
I was spinning the motor over by hand to bring it to TDC to install the distributor, well I always take my driver's side valve cover off to watch the valves open and shut. My first rotating to my TDC mark was 180* out (I saw a valve close instantly followed by a valve opening) and something didn't look right. I spun it back to the sweet spot just before the #1 cylinder would go through the exhaust stroke (where the valves are both shut at 180* out) and noticed my timing indicator was about 10* to the right of the TDC mark.
I verified my balancer isn't twisted by installing a piston stop and marking it at both sides and finding the center. It's some stupid aftermarket timing indicator on a stock timing cover; I assume some knucklehead installed the wrong indicator.
At the point of being 180* out (when the balancer shows at TDC but it would take another rotating to be correct) and both valves are closed on the #1 cylinder; can I use that spot to verify the indicator is not in the right spot?
