im doing the same thing..... heres what I found... Its best to find an 87 TBI system and grab EVERYTHING from the donor truck... the reason the 87 is desirable is they added the TBI as an add-on preparing fro 88's new body style so the harness/computer etc has its own seperate harness. I was planning on using an aftermarket 4bbl intake and making (i am a metals teacher) an adapter for the throtle body. you will also need an electric fuel pump unless you are going to retrofit a burb or blazer tank under the rear of the bed. I am planning on doing this to a 63 pu so I will have to add a return line from the TBI back to the tank... you should just be able to tie into your existing one. My only question yet is concerning the distributor and if there is a plug and play dist that can be used... not sure if the regular old HEI will work. Hopefully someone can answer that.... Hope that helps..
