As far as i can tell, this has a later model engine in it. You can separate it from the bell housing. It is not like the 235/216 engines. Remove the starter & 6 bolts around the perimeter of the BH. Pull the engine forward & raise it up. Leave rest of the stuff alone. Put a stand under the trans or tq. tube as it will drop a bit.
You can wrap the chain around the rear section of the intake manifold & the other end use a 3/8 coarse thread bolt & put it in the upper accessory mount hole on the right side of the head. If the manifold are off you can use a bolt like that in the manifold mount hole.
