    I have a 1990 2wd sierra and I am thinking of putting my race motor in it. It is a carb engine out of an 84 ish vehical. I believe i have the 4l60e tranny what does it need to have to work right as far as computer or will it work ok with out it? OR is this a bad idea and way more work than its worth? I have the motor sitting around since I dont race anymore and want to put it to use and make my truck fun. any help/ advise will be great
