Well there is new hope we will be able to do a gear swap. Only one I know that has pulled it off so for is Jim. The wavetrac, is a unit that replaces the spider gears, has nothing to do with gear ratios. It is a limited slip replacement. Any we have 1 V-8 conversion running a 3.27 vs the stock 3.07 in an SRT chassis. Only one I know of to date.
