I have a 1977 280 that started smoking badley i thought it was the head and gasket I rebuilt it and did nothing to the bottom end put it back together and it still smokes not as bad but smokes blue. I met a guy who gave me a stripped 74 260 with a complete engine transmission with down draft webers what should I do and what options do i have should i put the 260 engine into my 280, should i put the 280 head on the 260 block if I even can. any suggestions would be great tthanks Rhett. I have a 74 260 that I have had scince high school with webers and love it never had any trouble with it. the 280 always seemed to run to hot.
