Need 65 Barracuda info ** Updated **

65 models had a single reservoir master cylinder. It's good to upgrade to the 67 and later dual reservoir master cylinder for safety. If one line gets a hole in it, then the other system will work with the dual reservoir system. If a line gets a hole in it with the single reservoir master cylinder, it will take out all the brakes...

On the 2 bbl issue - most people go from 2 bbl to 4 bbl, not reverse. If it has a 2 bbl, check carefully to make sure it is an actual Formula S...

If it's an original commando engine, the commando valve covers will have the larger hole on both sides. The driver's side gets the large hole for the breather in the valve cover. The passenger side will also have a similar "pipe" coming out of the passenger side valve cover which will take the "stove pipe" style PCV valve.

The passenger side valve cover should have three small tabs for the wiring harness for 65. The 66 had the stove pipe PCV, but two small tabs for the wiring harness with a larger bracket for the wiring harness.

67 commando valve covers came with the newer style PCV which has a large hole, not a stove pipe on the passenger valve cover and the two small tabs and large bracket in the middle for the wiring harness...


65 Commando covers. Notice the large stove pipe in the middle of the right valve cover and the three small tabs for the wiring harness:

Here's the 67 Commando valve covers. Notice no stove pipe in the middle, it takes the big grommet and then the smaller PCV. Also notice the large bracket in the middle for the wiring harness:
