My dad had one
It was in the shop so much he had to buy a backup car.
As for driving it like a car - how could you? It had no balls and was routinely floored. It would lose a drag race with heavily loaded VW Microbus.
At about 30k miles the undersized hoses came apart, it vented all its steam, boiled itself dry, and melted down. My uncle (GMI grad - worked on the vette as auto engineer through the 60's-80's) told me that motor was a total kludge based on taking a regular 350 and trying to beef it up a bit.
Yeah, no shit.
I'm very pro-diesel (got a VW Pathfinder driving my boat) but not that one.
