Mopar Performance Distributor adjustable advance?

Trial and error it is. I just set it in the middle. From what I (just) read it's adjustable from 0-28 degrees?! So half that should be 14, so I'll see what it does with timing at 20 degrees. I'll see if I can find these tuning keys. Anyways, the distributor came with the engine and I had never really looked at it. I'm glad I did.

No, it's not trial and error. Get a grammar school protractor. Stick the rotor on. Put the protractor above the rotor so the tip or the rotor is pointing to zero. Now, twist the rotor advanced and see how many degrees you have. Multiply that times 2 and you have crankshaft degrees. So if you have 5 degrees at the distributor, that's 10 crank degrees. Get it? Screw that trial and error chit. And screw that FBO guy. lol
