'70 HemiCuda UPDATE:
I tracked down, and just got off the phone with, the "second" (mechanic) owner of the HemiCuda. He actually was the third owner. Two other fellows bought it ahead of him, and did a very quick and poor "in their garage" body/paint job, painting the car in gritty Purple AND BLACK, pulled the engine-only to be installed in a "non-Hemi Super Bee" (his recollection), and sold the rolling engineless chassis to the mechanic. When he realized how improperly the car had been "massaged", he lost interest and eventually sold it to someone in the Kitchener area...minus the engine but with the Hemi 727 and Shaker assembly.
Could the engine have ended up in the J-Code 'Runner? Or did it, in fact, go into the 'Runner instead of a Super Bee? Anything's possible...but the brothers who raced the 'Runner that summer, after torching the quarters, DID blow it's engine. And they're NOT the guys the mechanic bought the HemiCuda from. So, if the two were mated, it was later...somehow. I'll see what else I can uncover.
As mentioned, to many, they were "just old cars". Beaters to be beaten. Sad...but true.
But it IS a sad fact the HemiCuda and its number-match engine were separated. The fact the car was a full number-match car was what had me seriously interested in the first place. To some of us, "numbers" meant something...even then. Previous experience with Corvettes back in the '70s had taught me that much.
Today, of course, the VIN and the driveline alone would be worth pretty serious money...but that's 35 years later.
Again, thanks for your collective indulgences, and interest.
