The 3.8 is capable of safely producing 300rwhp with the aid of an M112 or Pro-charger. The engine runs perfect, and fortunately though the car suffered a bad enough warp in the crash to produce ripples in the top and completely move the passenger front tire back, the engine seems unharmed. So I have EVERYTHING to work with, hoping the little 3.8 fits betwen the shock towers, I also worry about the rear end fitting under the 68. I had visions of much much more power but 27mpg is too tempting to pass up. With 180hp and 215 ft/lbs of torque it will scoot along far better than its factory 200 inline ever did. The radiator and AC condensor even survived the crash. I think with 3.73 gears installed, a good tune, and F/I the little 3.8 will scoot the 68 coupe along fine, and produce a streetable go-anywhere package. My biggest worries are hooking up the instrument cluster, fabricating motor mounts, and getting a driveshaft to fit.
With all the money invested in buying the Vert and no way for it to get paid for funds will be cut off for the coupe, Or I can use whats availible to me and build the car. Im pretty sure this hasnt ever been done, the little 3.8 isnt a favorite engine, especially not for classics. But its very reliable, cheap to operate, and good with fuel. Plus 4 wheel discs, power steering, and AC are nice features.
