    shaun. come over and look at my buggy. lol. but idk if u have to leave the computer in. i took out all the stuff off of mine and the tranny still works fine. and it was in a 1991 k5 with a th350. idk about 700s tho?? if u do need it youd probably have to swap all the electronics (wire harness) and get an older tranny. idk tho. not sure?

    I used to tell people that I like my truck stupid..... no computer, no electronics and all...

    well now I am getting tired of adjusting my holley truck avenger.... or maybe cuz I never adjusted it right from the beginning. im not sure..... Id love to go fuel injection but dont wanna be bothered.... so I am tempting to just throw my qjet on the shelf on the truck... or adjust the holley.. we will find out this saturday when I have to work on the truck to get ready for inspection....

    I say keep the TBI it is a very simple setup. My 90 runs much better than my 86 ever did. Off camber situations it just keeps running. Just my 2 cents
