I'm not a big fan of the 88-91 throttle body injection systems. Had and seen too many that will rev to high heavens, and just not do what they are suppose to do. I would say anything 1987 on down (carbureted), or '92 and above. 1999 or above you will get a better overdrive tranny. '87 on down you would be getting a good ole' 727. Just my 2 cents, I would look for a '99 or above. Why? Because fuel injection is nice, especially in the winter, A/C is nice, OD is nice if you want to travel 70 mph, and these years are very easy to get, and price matches condition.
