Factory 68-71 340 727 specs

I have machined a few pressure plates to increase clutch plates. My swinger has 5 front clutches and 4 rear.
I also installed 4 pinion planets front and rear. If I recall, a 340 trans will have 4 pinion front and 3 pinion rear and same for the clutch packs.
Dont sweat rebuilding a mopar trans. They are the easiest of all the transmissions of the big three.
