fixite7, to guide our conversion back in a Stovebolt direction, to the best of my knowledge FiTech really doesn't have a unit that's marketed for our size engines. They do have a two barrel unit that's good for 400 hp. Will it work on a sub 100 hp engine. Perhaps, I really don't know. Holly's Snipper division has a one barrel they say is for 144ci to 300ci, 4 and 6 cylinder engines with throttle bore of 1.4375" and good for up to 175 hp. If I were considering Fi for one of Stovebolts with a original engine I'd give the Snipper a hard look.
My FiTech is on a 302 V8 (bored 60 so it's actually a 310) and is a 4 barrel throttle body that the uninformed would think is a 4 barrel carb. MPG hasn't been a concern but it runs from high teens to high 20's depending on how much fun I'm having in the little car.
