If it was my car I'd have the engine on the dyno over the winter so I had some data to work with. But it isn't my car and they don't want to pull the engine to put it on they dyno. The last time I was over at the chassis shop they were finishing up the four link install. It is probably finished and on the trailer by now. They are headed back to Bakersfield for the March meet so we'll see how it does there. For some reason it seems to run the best down there.
