'69 Turbo 400 code?

[Rowdy Rat]

Rick,

I figured it was a "big" Chevy from your previous posts... I gather that this is a 1969 L-72 car? Very cool if it is! I've been hunting for a 1969 L-72 Biscayne, Bel Air, or Impala for a while now... Not many out there as I'm sure you're aware. I'd love to hear more about your car when you get the opportunity.

I don't disagree with what you and others have located in print about the "CY" transmission usage with the 427/335. I would guess that it might be a mistake (unless the "CY" transmission used in this application is VERY different than the other applications listed). You mentioned that that this is a low horsepower engine; it is also a low rpm engine. I'm sure that someone will post the redline, but I'd be willing to bet that it is 5,500 rpm or less. With a redline (and powerband) that low, why do you need a transmission that shifts at 6200+ rpm? Logically it doesn't make much sense. I'd like to hear some feedback on this point as well...

Regards,
