I might get a new MSD Pro Billet dizzy for Christmas and i want to know yalls opinions on what i should get. Should i get the mech advance or the vacuum advance, what are the pros and cons of both. Also what are Wedge 460 heads, whats so special about them.
Merry Christmas :-X12

Stick with vacuum advance for the street...mechanical advance for the race track. Your engine can handle more advance under a light load (such as in street driving)and will make more power and get better milage with vacuum advance. Also when you get around to installing a different cam, dump the 650 and go for a 750 vacuum advance...your engine will require more CFM. Happy Holidays, Deen:-X12
