Ultimately it is your decision what to do with your car . . . I have always said, you gotta make the car for YOU !!! Personally, I would leave it how it was built. Probably get awesome gas mileage, and is totally NOT what someone else has !! At the end of the day, if someone wants it bad enough (i.e. dump in a 340, BB, or hemi and 4spd, etc) after you are done, then I am sure you can get MORE than your moneys worth out of the car. And being A93 with fixed rear windows - pretty rare !!!

I would think that there were far more slant 6 and 318 cars built, than the "muscle" versions . . . I am sure AlaskanTA would be able to give nubmers on that.

GREAT FIND !!! Good luck !!!
