Can anyone tell me what the application for a TH400 with a 71-CA on the tag is?

Thanks

For the Smallblock 400/255HP engine w/4bolt mains,denoted CLK when installed in any of the 1971 Impala series.

What trans ID tag would a 68 Gibb Nova have? CX or CY?

Just a couple of questions that have come up.
Would anyone have any info as to why GM put "CY" trans in the Impala's and Chevelle's
And the "CX" trans in the Camaro's and Nova's?
According to the chart on the first page of this thread the diff. between "CY" and "CX" are the case, and the "CX" case is the same as the Std case,and the valvebody.
Am I correct in assuming the valvebody to be different because of the weight of the Impala,and Chevelle being more than the Camaro's and Nova's
One more thing, did the Corvette's use the "CY"s also?
Thanks,Joe.

For 1969,is that a correct statement?..wasn't the CX early for all those Spcl.Hi-Perf equipped cars,later superceded by the CY for all those Spcl. Hi-Perf equipped cars?

I think there was a valvebody difference,but I'm not sure if that was it.
Thought the 427/430HP & 435Hp Corvettes did come with the CY,as of April 69.

Sorry, Yes this would be for '69.This what I am trying to find out,was there a change mid- prodution or were they both used all the way through from start of 1968.If there was a change,do you know what date this happened,Thanks.Joe.
