Holley Sniper vs. Edelbrock Pro-Flo 4

A dual sync should be fine for most engines. I've used dual syncs on race engines even though the conventional wisdom is to switch to a crank trigger for racing. I use a crank trigger on my Duster engine with coils but that is kind of overkill for a street engine. It looks cool and it works great but it isn't really needed.

Mopar was going to sell a dual sync distributor for Magnum swaps, but it never hit the market. They even listed it in the catalog in the description of the 380 HP EFI swap kit (I think). I asked one of the engineers about it once and he said it took special equipment to get it all sync'ed so they dropped it.

I wouldn't mind figuring out a dual sync distributor for my Magnum EFI swap, but already built a crank trigger to duplicate the factory signal so probably too late.
