i want to do this to my 91 bird this winter, i would like simply take out my 305, and swap a 350 under my tbi set-up, of course add a more powerful cam and headers, etc. but what would need to be done to the comp, and injectors to do this swap? I want to use my tbi set-up, and not just throw a 4 barrel on it. im sure some of you guys had done this swap before, ive always gotten good advise from people on this board so thanx in advance for any help

Custom Chip is best,but you may not need it,depends mostly on cam.Should be able to use same computer with either custom chip or I keep hearing about a stock Caprice chip that'll work,but I don't really have any details on that.Anybody?
Some say the stock chip in the computer you have will work with some fuel pressure increase.
