Mopar Proformance Distributor

your post makes no sense whatsoever jeff,the M.P. distributers do come with the fast curve built in,between 2000 and and 2500 rpm. why would the magnum heads require less mechanical advance? so ya run 15 in the distributor and 35 total meaning your running with vacuum advance 50 degrees total, wrong,jefflock just buy the M.P. distributor and refer to the rich carb thread for proper procedures.who cares what the initial is ? its all in the distributor and on a performance engine ita always total,never initial, you got bum info friend.
