69 COPO chevelle buildsheet

[JoeC]

The engine code for a COPO Chevelle TH400 is MP The 4sp is MQ.

The 1969 COPO Chevelle is # 9562 with eight different ECL codes (AA,BA,CD,CE,DD,DE,EA,FA)that specified the combination of the transmission, the seats, the springs, and the tires. In addition to the eight 9562 XX codes Chevy added two more - the 9566 AA and 9566 BA which are the same as the 9562 EA and 9562 FA combinations with the exception of tires. That makes a total of ten COPO numbers for the 1969 Chevelles. Yenko added his COPO 9737 (which included the 15x7 Wheels) to use as a combination with the COPO option 9562. The Yenko Chevelle is a double COPO. This is from the Chevy documentation that is included in Ed's COPO book.

The engine suffix code for a 1969 chevelle four speed is MQ. The engine suffix code for a 1969 chevelle auto is MP. If you are using Alan Colvin book to ID these numbers, he has a misprint on page 51 of his book. I have my build sheet plus several others which confirm this. I would post some examples but I dont know how to do that yet. Back to the build sheet at team chevelle sight, this sheet is not set up like any of the ones whick I am looking at.

As to the 9562XX, none of the 56 COPO's I have longed, have that code, all are 9566XX. Many of the copies I have, include Z codes, which I have most, if not all, broken down. My COPO Chevelle,with build sheet, has Four Z codes. It is a very load car, compared to most,(2 like it). If any one has a build sheet with the 9562XX, I would like to see/talk to you. I beleive this was the early stages, for the CHEVELLE.

Thanks guys, was using Colvin's book as well and was unaware of the misprint. Ed Cunneen's COPO Connection book shows 9562BA for an auto COPO Chevelle, but perhaps it is a misprint as well. this is from a Chevrolet memo date 8/2/69

A69COPO2 - Are you saying you have 56 COPO Chevelle build sheets? Are any of them Yenko Chevelles? I have a few build sheets for Yenko Chevelles and they have the both the 9562 and the 9737 number on them. They are not early cars. (June/July) I have some for COPO Chevelles (non Yenko) and they have the 9566.
COPO - The COPO Connection book shows 9562BA as a TH400 car and is not a misprint. The 9562BA, 9562DD, 9562DE, 9562FA, and 9566 BA are all TH400 cars according to the Chevy letter on page III-13 in Ed's book. They have different combinations of springs, seats, and tires, but are all auto trans.

Joe, the sheets I have for Yenko Chevelles do have the 9562 and 9737, along with the correct alpha code after these numbers. None of them have the 9566. Some of these sheets also list other numbers ie 9694, 9562(none of mine have the XX sorry A69COPO). Back to the MP, MQ question Ed has it correct in his book page 78. I am not a NOVA guy but I think Ed has the CTB and the CTC mixed up in his book same page 78.
