MP DISTRIBUTOR TIMING CURVE 340

CFD244 said
There are 2 ports on the rear of the TQ. The one closest to the pull off supplies metered vacuum to the pull off/dashpot and the one beside that is manifold vacuum, and where the vc gets connected to. The timed port is at the front of the carb.,and in this case, gets plugged.

I am using a 6139.....Fuel metered 1972 model.

So do yourself a favor.
Hook the ported port on your carb, to the vacuum advance like it was designed. Set your timing between 12-14 initial 34-36 all in. And watch it purr like a kitten. And your cam is close to stock, so there should be no issues with idling.
