Ok guys here's the low down. I've got a boat with a 460 in it. being rebuilt. I"m doing a tpi swap on my blazer. the boat came with a holley carb. but I've been doing all this FI research and got to thinking about swapping the boat over as well and be done with carbs. Posted this on pirate in the ford section and a guy mentioned using a tbi unit off a 454 and just adapting it since these are fairly close in displacment. So I"m asking everyone here for input on what I would need to do this.
