I have a spacer under mine, it has the PCV connection on it. I have a Ford hi-rise intake with the 4100. no clearence issues on mine, a 65, but is there an engine height difference with later motor mounts?
Your spacer should have a C4OE casting number on the underside. That spacer fits all Mustangs, Falcons and Mustangs with 4V carbs in that era. The nipple on the rear for the PCV hose will sometimes be drilled out and sometimes not depending on the emissions requirements where the car was first sold. Even ones that are drilled our for the hose may be capped with a rubber cap and spring clamp. These are generally service replacement parts.

Not sure if all of them had it, but 68 Shelby small blocks with the Cobra intake had a thin phenolic spacer with a PCV nipple on the back (very prone to cracking).
Quote from 66gtkI also heard the GT350's with the high rise manifold DO NOT use a spacer. Is that also correct?
Correct, 65-66 GT350's did not use a spacer. I'm pretty sure 67's didn't either.
The aluminum intake motors didn't have spacer under carb.They had a thick gasket that had 4 plastic washers built into the gasket to keep carb off base of intake and aligned the carb studs.Kinda hard to find.
When I was addressing the spacer issue I was under the impression that Troy was using a stock cast iron manifold. My reply was not trying to address a high rise aluminum manifold. The Shelby manifolds have hole for a fitting in the rear of the manifold for the PCV hose if one was used. Other posters have established that a C4OE spacer was not used with a Shelby manifold.
