Spent a bit of time today fabricating a PCV line (from a new piece of 3/8" steel brake line) for the replacement Holley 4160 carburetor:



The original setup had a 1/2" rubber line running to the back of the Autolite 4300A carb, and a matching 1/2" PCV valve:



I copied the 3/8" design from the '78 and '79 400 CID's in the Lincolns, which run the Autolite 2150 2-barrel. The PCV valve on the Mustang was also swapped to the Lincoln-spec.:
