Hey guys! I brought this up awhile back but had to put the project off until now. I'm replacing the distributor on my 78 F-250 4x4 due to a blown vacuum advance diaphragm. The wires have also been hacked up a bit and the screws for the vacuum canister broke when I tried to remove them, so I'm just gonna buy a reman unit. The current distributor is a dual advance unit. Would I benefit more from a single or just stick with a dual. Engine has a mild edelbrock cam and intake with a demon 625 carb. Would also like to purchase a recurve kit before installing. All replies are appreciated, thanks!

 

Personally, I would use a single advance.

 

. If you want some MPG, stick with the dual advance...
