I loved the slant 6, most came with really nice car bodies. I loved to pull the slant 6 and its attached trans out and replace them with V8s.

Probably not the kind of love your looking for though.

We had a 225 with a 3 on the tree in a 65 Barracuda. It was kind of fun to drive, but I bought it in a package deal with a 318 4 speed in a 65 Barracuda. The slant 6 wasn't near as much fun as the 318 was. I did pull the few parts off the slant 6 car I needed for the V8 car, and the guy I sold the running and driving slant 6 car to loved it and drove it several years.
