Yenko 427 Engine Information
I have a 427 L72 Yenko complete engine in my car. Does anyone have any information or links that can provide more info. It has the Yenko located in the block casting front drivers' side on an angle. The heads are cast 3946074. The intake has the winter foundry marks. I understand this block casting was from earlier blocks, possibly 69?
