Mancuso Deuce yanking 'em off the ground!

[YENKO DEUCE REGISTRY]

Pete;
I think you are right on the money, the deuces were the same price as the L72's from '69 and the dealers did not want to get stuck with more high-priced inventory. Yenko Chev. still had 3 deuces on 1/1/71, H&H had one in Nebraska, Rapids Chev still had some I think, and Colonial had a whole bunch of them left. So, after the initial sales flurry of deuces, (several were sold within weeks of hitting the show floor), the remainder of them did prove difficult to sell.

JoeC;
NHRA has never classified the '70 Nova with an LT1. The NAAR in Oakmont, PA did classify it in F/Stock.
