I am looking at a engine that is for sale and the guy Won it at a Mustang event. He doesnt know much about it. I looked it over good and the rebuild seems to be good to go. The pistons are .030 overbore. With that being said I can get a killer deal on this motor. I will probably pull the cam and put a better suited one in for my Bronco application. What I am trying to figure out is what year this motor may be. There are no markings or casting numbers on the block except where the intake lays on the back of the block and half of that is machined off. I am guessing its later than 74 as the block does not have the mounting casting for the clutch bell crank. The motor was built by AER. The metal tag they put on the motor says *34751*
