Going from carbs to FI is a big step for a rodder. Go to any car show and you will see very few of the hot rod folks step up to FI on the retro cars and trucks. I have a '62 short bed with an IROC camaro FI in it and it is the only one in a rather large city. It is challenging. You have to plan for a pressurized fuel system, a relay system so that your ignition can deal with the extra amps on 12 v. power, a return fuel line, hiding wires so it doesn't look like a mess, etc. etc. I think there will come a day when carbs are not in vogue, and FI will be the standard. Do it. You will be in the 21st century and will learn a lot.
