I'm trying to figure out if my '50 3600 has the 216 in it, or a later model 6. Here are some casting #'s.....
Cyl. Head--- 3835913/GM20
913/241/570
Block--- 9836236
Exhaust Manifold--- 8335580
What has me wondering is the valve cover. It has the Chevrolet script across the top, rather than the regular "ribbed" cover. It is still running the generator & road draft tube, if that means anything. Thanks in advance for the help.
