Was just over at my friends body shop. Customer had just brought in a truck frame for him to install the cab he has completely reworked. Big block motor and 727 installed. I was looking it over, and on the pass. side the date code showed 12-8-70, and the driver side numbers showed 430. Thought I was seeing things, so I had my nephew look. ???? Customer told him it's a 440, and it does have a cross ram intake on it. It is going to make one nice '65 truck. What is this?
