The most "significant" Chevrolet performance car.

[Canada George]

Verne,

Nothing up my sleeve, I assure you! It’s not my intention to trick anybody.

Getting little response makes me think the question needs to be clarified. Either that or I really did load a cat in a bag (maybe to take it somewhere it doesn’t WANT to go?) .

I believe it is widely accepted that Chevrolet in the ‘60s and early ‘70s produced a few levels of high-performance ENGINES. One level has been referred to as the “big block street high-performance” engines: the “solid-lifters”, L78/L72/LS6.

They also made available more highly-specialized, heavy-duty full-competition RACING engines. These motors were all high-compression (12:1+) requiring racing gas and otherwise designed and specified as off-road use only. This very short list includes the Z11 “W”427, the L88 and ZL1 427 and the LS7 454.

Does anyone know if there are any other Chevy power plants that would make this list and if so were they available factory-installed to the public?

If not (to reiterate):

Would you agree that the Z11 Impala, the L88/ZL1 Corvette and ZL1 Camaro are the ONLY factory-built FULL-RACE engined cars made by Chevrolet and made available to the public, during the performance years?

Any car that would measure up to this yardstick would surely qualify as a “significant” Chevrolet performance car, amongst the others already mentioned.

HAPPY MEMORIAL DAY TO OUR AMERICAN FRIENDS!
