I have a 85 d150 im wanting to upgrade the distributor im looking at the pro billet MSD street fire /coil 6al.(includes msd coil 5520 digital box w adjustable rev limiter and of coarse msd pro billet dist ) Will this better benefit me over a reg msd distributor? the motor is a 360 30 over w a mild cam.

 

It will work out just fine for you. I built an AMC 360 (cam, pistons, intake, head work, etc) and went with an MSD Ready-To-Run diizy and a blaster 2 coil. Never had any issues.
