OK I am sorry if this is a stupid question but I am kind of at a brick wall
I have a 70 something 351w in my boat the problem I have is this I am trying to set the timing however do to the water cooling system I am unable to bring the vacuum advance around And am kind of stuck as the timing is so retarded that runs hot at ideal
Manifold is engine vaccum . Ported is only supplied at throttle command through the carb . I would think you could find a vac port somewhere on the carb or intake that is full engine vaccum . Of corse vac varries with engine load . Wot = less vac ,part or closed throttle = more vac .
Hook your advance to manifold insted of ported vaccum . That will advance it . Then bump down your timing as needed . a thought ?
If his timing is retarded now, then you're taking him in the wrong direction. He just needs to reset the initial timing. to accomplish what he's trying to do.

If he hooks to manifold vac , that will advance his timing at idle . I got that he could not advance any more because of clerance issues with the coolant crossover assy between the exaust manifolds .
Done it a few times myself, it'll work. You're moving the wire positions 45 degrees without touching the distributor itself, you then can pull back what's needed by adjusting the distributor.
