Hi, I'm in the process of converting to FI on a 455. I found a 2bbl iron manifold from a 70 olds 98 that is in good shape and bored out the carb base to 2" for a TBI from a gm 454, it is a bit higher than the original but I think I can fit it without raising the hatch. I already have the TBI, which I was going to control with megasquirt. I also have a set of port injectors from a ford 460. Now i'm thinking maybe I should go to port injection to try to squeeze out another point or two of fuel economy. Is it worth the extra work. (bore manifold, fuel rail, plumbing etc.) Opinions?
