j hancock Posted July 29, 2015 Share Posted July 29, 2015 The block tag is on the right side of the block. It may be tough to see with the truck side panels in place and around the air cleaner assembly."6" is the series of chassis."11" is the type of engine originally fitted. Probably a 250-260 hp.
