I sent my distributor out to be recurved. This thing has been giving me major tuning and timing issues since I bought the car.
The person I sent it too is someone from the NCRS discussion board who has a Sun distributor machine.
From past experiences already I really HATED the idea of sending anything else out to anyone, but I knew that i'd never get this thing fixed correctly without it being on a Sun machine so had no real choice and NO ONE, i mean NO ONE local has a Sun machine.
well, he recieved the distributor today and looked it over. He hasn't even gotten it on his Sun machine yet but already said he sees some major issues with it.
first of all, he says the cam assembly is not the correct one is is actually off a '69 truck!! that itself goes a long way in explaining why the curve is all wrong and is too long (too many degrees of advance). I knew from my own readings that it was giving me 32* of mechanical advance rather than the correct 24*. The good news is he says he has the correct cam assembly I need or at least one very close to it. That should make a big difference right there.
One other thing is he noticed was it has a later model style rotor on it than the '65-66 cars used. The difference, (other than color) is the tip is about 1/16 of an inch shorter than the 60's style moving it that much farther away from the pin in the distributor cap. Requires higher voltage to jump the gap from the tip of the rotor to the pin in the cap that connects to the wires.
I just bought that rotor from Paragon and installed it in Dec but if it's wrong it's wrong and he will install a correct one.
He should have it on the Sun machine Wed and we will see what else he finds.
