1966 Mustang with 1986 EFI engine, Valve cover question?

woods66 · 3 Weeks Ago

Ok i am almost ready to drop my new engine into my 66' mustang. I got this engine out of a 86' mustang GT. so it is a roller engine. I just need to know what valve covers to use, because the factory 86' covers have no pcv holes cut in them to releive pressure in the engine. any help would be great!

The factory cover on the oil fill neck has a hose to vent into the trhottle body, if you are going with a carburator, route a hose from this spot on the passenger side cover to the Air cleaner.
I dont know what covers fit an 86 but I am sure sumittracing.com will have you covered(no pun intended)

if you are going carbureted with this engine then any 289 or 302 valve cover you happen to like will work fine. the reason the 5.0 valve covers are specific is because many of them interfere with the upper intake manifold. but with a carb that is a non issue.
