Anyone know what the part number is for the factory forged pistons that were in the late 80's and early 90's 5.0's? Also, does anyone know if they were the same bottom end as a mark 7... I know the crank is the same, but can't get the ford casting number to come up with forged or not... Thanks

the mark VII's from 87 and used the same block and rotating assembly as the mustang. the conventional t-bird and full size cars and trucks used cast pistons.
