I think you are on to something but with a twist. I have no problem with the 4.3 v6,as that is whats in my Syclone,but then again thats not a normal 4.3. Here is what I would suggest: Chevy also made a 4.3 v8,and if I was looking for good power with outstanding gas milage,that is what I would use. Some call it a "baby" LT1 because they look the same. You could get them in 94-96 full size chevys and would produce mid to high 20's for gas milage in the original cars. They are overlooked by many swappers as they want an LT1 with 350 cu inches. If it interests you,look for a 94-96 where the 8th digit "is not P",as P signifies the LT1. FWIW
