Timing question

Yes we disconnected and plugged the vac advance. Carb was off choke, but RPM's were up due to cam break in.

This is what we were trying to do with the timing though. Even now, with the rotor and the spark plug wire both pointing at cyl 1 the timing mark on the balancer is no longer at 0 it's at -5...

Maybe we were having trouble because we were trying to time it with the RPMs at about 2k during cam break in? Idk really, this thread is essentially for me to learn more when the smarter guy isnt here and I'm supposed to be studying for a final exam tomorrow morning. I just cant get the damn car off my mind though...

What year is your 340? 68? Is the balancer correct for that timing cover or did you guys mark it?
