427 Chevelle Question

[BigD69]

I'm in a disagreement with a buddie who says Chevrolet made a factory 427 Chevelle in 1966 and 1967, I don't think so, who is correct?

[SS427]

NO ONE has EVER come up with ANY proof that Chevrolet built a 66 or 67 427 Chevelle due to the 400 cubic inch rule though many have claimed it. On the other hand, MANY dealers did 427 Chevelle swaps in that era. I knew of a few myself. This has been a long standing argument on the Chevelle community for many years.

1966/1967 427 Chevelle . . . Urban Legend . . . along with 1965 327/375 HP F. I. Chevy II, Chevelle and El Camino

1966 and 1967 General Motors production documents show no production of a 427 motor in either year.

You can never really "win" these arguments, because there is always the guy out there that insists that the factory would build anything you wanted back in the day.

As if a production line cranking out millions of cars is going to stop and do special requests (not to mention the Engineering, supply chain logistics, etc involved with something as significant as a different engine).

Not to be argumentative, but isn't that what COPO essentially did?

"Experts." I stopped hanging around my cars at shows because of "experts" who would talk you to death if you let them.

Not sure I understand that as their were 427's in Corvettes and big cars as well starting in late '66.

----Late 65, Mark! And, to add to that, there were test 427 vehicles in 1965, mainly 1965 Corvettes, a few of which escaped the factory into private hands. One specific 65 was serial # 5 off the assembly line. It was initially built as a fuel injected roadster but taken to the tech center and had a 427 transplant. The car is fairly well known in Corvette circles. I have seen and inspected it closely.......Bill S
