So we had to install the intake right away for a couple of reasons. One, we wanted to see it on the motor and two, we knew there was going to be an interference with our catch can breather setup. We’re using some 83 Mustang 5.0 valve covers we scored from a friend which are taller and have screw in cap provisions for the breathers. Standard fare on any 83-85 Mustang 5.0.

Note how close that breather insert is in that front right valve cover. And that’s using one that’s specific to an old Bronco which is shorter than the one on the back left that is stock to the 83-85 Mustang 5.0. So obviously the next challenge is getting that breather solved to complete the catch can. I know that I’m being hard headed with this and that a simple solution would be to just go get another set of valve covers and weld in a couple of bungs and then connect some quick connects to it and call it a day. But, that’s not what I want to do. So I’ll work to find that solution or make one. What I don’t want to do is modify the valve cover itself.
