myfather-in-law just passed away and he was installing this motor into a 84 mustang for some reason, he was an odd guy. He had told people that it was a Boss engine he was intalling into it and he spent $5000 getting it restored, the enigine not the car. I know little of engines but i was able to get a number off the back of the block it was
RF-E3ZE-9425-FC. the carb from what i am told was just on there to test the motor and the original carb is still in the garage.
thanks jeff

 

did you get that number from behind the starter. I never saw a ford part number start with RF- but the rest on that number decodes as a engine part from a 83 mustang the block numer should be -6015-.

 

ford used the slogan the boss is back in 82-83 probably a 302 out of a gt not a boss though a boss motor would have to start with c9(1969) or D0(1970)

 

LOL @ this thread

 

Just look at the freeze plugs, Boss blocks were the only ones from the factory to have screw in freeze plugs.
