One of the main purposes of this conversion would be to obtain positive traction. One other main benifit would be that there are commonly available gearsets for a lot less with a large variety of ratios to choose from. The decrease in weight is a fringe benifit.

This particular individual (not me) was kind enough to share his experience with me. The list requested that I pass on any info I got so I replied to the list with the two posts that were emailed to me directly. This conversion cost him $2000. It might not cost that much. I guess it all depends on ones resources and the determination to do it. The '80-82 corvette unit is supposed to be a aluminum dana 44 unit. I believe you can buy a variety of gear ratios for this setup for less than $200. The unit should also already have a posi. I personally have located a source that would sell the unit for less than $400. This is a good reason to pursue all avenues before a decision is made.
