Have to wonder why.

The only person known to have worked on the project outside of Chevrolet was Smokey Yunick. In three different articles over the years, he stated the Hemi 302 topped out at around 450 hp. The intake port design compromised exhaust flow.

The small-block hemi head was never released for production or used in competition. It's likely all the parts in existence came from Smokey Yunick's auction.

Over the years I have seen a few Z/28 built with the Hemi 302, one in The Shed collection. Not like he would be the first.

As far as I was told, Bob bought both of the running test cars at the auction. 1 1968 and 1 1969, both dressed as Z/28's. Last I was up there, they were both there, but that's been several years now. The 3rd engine was on a stand at the auction and Bob told me Vic Edelbrock bought that one.
