Converting to FI is a great plan if you aren't in CA. It cannot be done without swapping in and entire FI motor from a newer year truck. Trust me I have been all over this with the smog referees! CA laws suck for motor upgrades. Swapping is about the only option and you have to be really careful and get every part of the newer donor vehicle's system, sometimes all the way down to the fuel pump. Only exception to this is the GM E-rod motor. God bless GM for doing that. Its the only motor that is CA smog legal to put in any year vehicle currently on the road.
