distributor intermeadiate shaft?

moved the engine so that the timing marks on the balancer and the timing chain cover line up...

pop distributor cap to see if rotor is lined up with no 1 on distributor cap...

how old is your balancer? the outer ring on the balancer might have slipped if it really old...i had a 318 do that...could not time with a line...but ran great went timed by ear....

the outer ring had slipped....

so make sure no 1 on the balancer is no 1 on the distributor....
