Issues with 340 distributor

Will work with any 340 no matter what setup? Quality distributor? Also how is the curve adjusted? I dont know if the one i had was adjusted correctly. The one i had was a vacuum and machamical advance

Give him a shout. He will tell you all about them. It is a Mopar reman electronic distributor that he puts a custom curve in and the 4 seconds flat advance limiter plate. He will need to know your engine combo though.
