I am working on the distributor for the 340. First off... this housing is cast iron! I’m a Ford guy. Our stuff is aluminum. Anyway...
I have the unit apart. It’s a dual points unit. Stock for the 340. I am going to switch it over to Pertronix. The shaft and bushings are tight. Everything needs degreased, but all the hard parts are in good shape.
Unfortunately, the advance parts have a couple issues. First, the mechanical advance springs are shot. Need new ones. Second, I think the vacuum canister is shot. It won’t pull with vacuum from my vacuum pump. Finally, I have no idea which Pertronix to use.
I see the vacuum canister at Mancini’s. Good god that’s not cheap. Between that, the springs, and what I am guessing is a $125 Pertronix kit, I can darn near just buy a new Pertronix distributor. Am I missing something?
