Yes I had a Z with one of those engines. No they never came in a Car. My understanding is this engine was in a Z28 but it was not in the Z28 from the factory. I think they traded out a experimental aluminum blocked smallblock so the Z28 still has a unique engine in it. Reggie Jackson has one of these engines sitting on his shop floor. He also had a running one in a Z28. There is also a 68 Z28 with one in it. There are a few. Mine was in a yellow RS Z28. It can be found in May 2003 Super Chevy.

I've seen the engine Reggie has at his shop several years back here in Monterey...
