Folks, incase any of you are wondering, I replaced the 2150 carb with a FITECH Go EFI. It was incredibly easy. I have gotten about 30 more HP. An additional 3-5 mpg's. Engine started on first try, ran like Krap but after some timing adjustments it has been flawless. It's attached to a 360 with an Edelbrock intake. Strongly recommend it to all of you.
