LD340 Can’t Get The Carb Base To Seal

After putting these parts on, I tried to dial the timing in and discovered that I’m getting no advance from the distributor, I have it set at 10 degrees BTC at idle and it stays at 10 degrees when increasing the engine speed. I’m using and old MOPAR Prestolite tach drive distributor that came with the engine and am using a stock coil and wires and one of those blue hi rev ignition modules.
I’m going to replace the distributor with something newer / better, what’s a decent distributor to get for a car that’s just going to be street driven?

It looks like the cover for the tach output is contacting the intake manifold. So spin it around so its facing back and reset the spark plug wires.
If that set up is the same as the later P-part tach drive distributors, then timing has to be set at mid rpm - something around 3000. Then the way those were set up back then, most racers just accepted the idle timing for whatever it was. You can search for posts about the MP tach drive distributors where I've posted the advance curve.
Bottom line is IF the primary advance is real quick like the later ones, and your checking at a high idle speed - like 1200 rpm, most of the advance is practically done.
Knowing the rpm of the timing measurements is critical to figuring out what the advance is doing.

For street use, a distributor with vac advance and the proper mechanical advance will provide better milage and be easier to tune.
Whether you want points or a electronic version, message @halifaxhops and maybe you can work out a deal.
Advantage in working with him is that he can set up an advance curve.
