I have a 322 nailhead that I’m installing in a model A roadster. Has anyone ever used a Corvette generator tach drive set up on a nailhead? If so, what are some technical modifications if any?
I see that no one has chimed in here since yesterday, I believe that if you have the Corvette generator it's just a simple swap of replacing generators. Some generators are longer/shorter than others so the bracket needs to match. That's what I think, good luck. Pat
I would imagine your crank pulley will need to be the same diameter as the Corvette one, if it's different then you will be over/under driving the tach. You could be real slick and machine up a bolt on V-groove in the proper diameter that attaches to the Buick pulley and then space out the generator accordingly to line it up if necessary.
It may also depend on if your tach spins at a different rpm than the Corvette tach for a given RPM on the dial.
corvette generator drive tachs are 1:1 where dist drive tachs are 2:1, so you will either need a 1:1 tach or a ratio adapter in the cable
On the 2 to 1 drive which is the 2 and which is the 1? 2 turns on the distributor to 1 on the tach? Or the other way around.
