What are the favorable years of make ?

The newer the better? Im not exactly sure on any years that were supposedly stronger than others. I would go for lower miles before anything else really. At the cost of having one rebuilt, you can buy a warrantied unit through Bowtie or TCI for a few hundred dollars more. A full rebuild for a 700r4 in an 85 Corvette ran us around $1200.
