No dummy. How da hell you gonna get THAT over the crank flange? A split seal is still one piece. Although Tim Meyer does offer a one piece seal with no split for the 335 Cleveland engines. I have one in my 400. Narry a drop. The crank flange on the Fords are made so you can install one on buildup.
look sizzle chest, i don't know what kinda ferd junk might'en be rolling around in that cavern between your ears and ya could be conflating it with mopar!
