Well , it wasn't running when I bought it so I had no idea what I was getting....It was setting awhile....kids broke out drivers quarter window......got her running as some valves were stuck open and also put on a new carb....Then wouldn't go into reverse....broken reverse band....so now I have the tranny out currently for rebuild.....I am sticking with the slant for gas mileage as a DD....I can always change it out to a small block or big block in a few years....
