In the quest for a lighter and cheaper car, I want something different. Did the General ever build a 4 cyl engine that the 200-4R will bolt to. Mine has the dual bolt pattern. I just sunk a lot of cash into mine and don't really want to sell it with the car its in now. Just putting feelers out for possibilities. Wanted to build something reeealy light and thought a little 4-banger with 'round 30 # boost would push a 2000 # car with ease. Any thoughts? -Chuck
