This is my 1966 Chevy C-10 Stepside. I have done all of the work myself, including the paint. It has a 307 engine with a turbo 400 transmission. It had a smallblock 400 in it for a while, but you know how those 400's just love to overheat. I was out of town in heavy stop and go traffic, and guess what my water temperature got up to. 250 degrees!!!!!!!!!!!! CRACK.....BOOM.....BAM.....Motor was done. Oh Well.
