If you are talking about big V-8s, Chevrolet never sold a hemi. Some of the smaller 4 and 6 cylinder engines might be considered hemis, but the closest Chevy production V-8 to a hemi is the big block 396, 427 and 454 "semi" hemis. These engines had nearly hemisperical combustion chambers but unlike a true hemi, the spark plug is not placed at the top of the domed cylinder head.
There are presistant rumors that in the 1960s Chevrolet was developing a hemi head for their big block "rat" motor. There were undoubtedly engineering concepts build inside Chevrolet's engineering departments. They never saw the light of day, probably because Chevrolet didn't see a need for the heads. NASCAR outlawed hemi heads in the mid '60s, so there was no need to develop a hemi for the super speedways.
The 454 Chevelles and Novas were the equal of anything ont the street, so there was no need to spend money on developing a hemi head for those cars.
Hemis were popular in drag racing circles, but the rat motor was able to hold it's own, until people like Kieth Black and Ed Donovan started buiding special aluminum racing engines specially fro drag racing.
In the early '70s, a racer named Nick Arias started producing custom aluminum hemi heads for the Chevy big block engine. These were true hemi heads, but they were not produced by Chevrolet or General Motors. Did Chevrolet provide any enginering help for Arias? If they did they never clained any reponsibilty.
Nick Arias Jr. has recently reintroduced the Chevy hemi heads, and is now selling complete Chevy head engines for the aftermarket.

Muscle car what did a 440 hemi cuda run in a quarter mile?
The 440, was a wedge motor. The Hemi, was a 426. They made a 392, but it was not for high performance. The hemi cars, were lucky to run in the 12's. Actually, the hot ticket for Dodge was the "max wedge," which was much faster. The Hemi was really quite a dissapointment, and most were pulled out, and trashed, or blown up. They could be beat with a small block Chevy. I know that for fact.........
