Cngrats, my first new car was , u guessed it. a 68 form S 383 fastback. wore the rear tires out on it and traded it for a 69 coronet rt 440 4 speed dodge. Drove for about a yr and a half, and traded it for a 427 corvette stingray, drove it about 23 hrs and sold it. I always wanted a 68 fastback ever since. After about 7 yrs in the making, I now have a 505' , alum. headed, fuel inj., 4 wheel disc brakes, 1968, orig. form S fastback . If u put a r/b block in it, I would do a 400 block, and not use raised port heads. I did and it sure is tite !! I`m not comp. savy either, so, no pics , other than my avatar here and on fbbo. good luck.-----bob
