[YENKO DEUCE REGISTRY]

To my knowledge, there is no documentation from Don Yenko and his thoughts on the 'vette LT1. The prevailing thought was that Yenko was simply following his previous model by putting the highest performing 'vette engine in a non-vette automobile - in '70 he chose the Nova to avoid the insurance scrutiny. I'm not convinced that Don did a lot of due diligence on the LT1, he saw 370HP in a 3180 lb car and knew he had a winner - so he submitted the combo for COPO approval. The kick was getting the 4.10 rear, as it was not an RPO in '70.
