[YENKO DEUCE REGISTRY]

Keith;
I don't know of any 'build' sheets in the Novas, however, there are several '70 Yenko Novas with their Broadcast Sheets. Unfortunately, these don't look anything like the '69 Chevelle Build Sheets which show the COPO numbers, special engine/rear codes, and on Yenko Chevelles are stamped 'Yenko' at the bottom.

The '70 COPO/Yenko Nova broadcast sheets do not have any engine code on them, even though they were spec'd out with an L65 engine; 350/265HP, which was later over-ridden with the LT1 via COPO 9010. Joe C. explains elsewhere on this site why the sheets show an M20 trans when the cars were really M21's. There is actually very little info on these broadcast sheets, and there is nothing on them about any COPO numbers. Makes them even more confusing to decipher.
