Mattax,
It works for everybody, not just me. It works on Chrysler engines. It will also work for you...

But let me hasten to add this: if you are using a locked dist, or some other means that provides a LOT of init adv, then, you probably do not need MVA. Or just adding a few degrees might be optimum. And you can add too much. Unfortunately, I have NEVER seen a detailed procedure to dial in MVA. And here in lies the problem, with no detailed procedure that is correct [ the Accel, Crane instructions are useless ] MVA is often incorrectly dialled in. When it doesn't work, the word goes out. 'MVA doesn't work'. An analogy is Bill gets a wheel alignment & afterwards the car pulls to the left & he says 'Wheel alignments do not work'. I developed my own method for dialling in MVA, it works EVERY time & will on your engine, subject to the above.

Don't know to load documents onto these sites, but if you PM an email address, happy to email the MVA info on Pontiacs & other useful info.
