Just an update on this.... Since the transmission is out of the car and going through a complete overhaul, we decided to go ahead and order the Trango 1&2 kit and install it instead of the SK400. I feel the final result will be much better, since this is a performance street application. Now we will have to decide what size to drill the 2nd and 3rd feed holes in the plate and which PR spring to use. Below is the whole combination, if Cliff or anyone else is interested in throwing out some recommendations on what would work good with this
