Procomp electronic connecting rods ?

Video link is not working but i had a set of worn out Bill Miller 426 AL rods and they were HUGE! Im suprised they fit but they have to be big as AL is not as strong as steel in volume. I gave them to a gearhead friend and he polished them and uses them as tap handles in his mancave bar. Guy has stainless derby headers on his BBQ/smoker!
