A friend of mine has a '68 Z that he's had for years and years, but its without the original motor, actually ANY motor...I'll track down his numbers and see if maybe, just maybe his motor is around here.
Unfortunately, he's one of those guys that will never sell anything, and if a motor costs $2000, but will make the value of his car go up $20,000, he sees that as losing $2,000 out of pocket. Very frustrating to see....
