Shaker Hood Scoop Base Identification

by Dave Schmitt

The highly desirable Shaker option was available on Mustangs for only two years, 1969 and 1970. BOSS 302 Mustangs had the Shaker available only in 1970. Shakers were available for the following engines, 351W, 351C, 390HP, 428 Cobra Jet, and the BOSS 302. Mustangs that came with the Shaker option used the same hoods. The difference in dimension and location was "adjusted" by using different Shaker bases for the different engines, locating the scoop in the same location in relation to the hood.

Descriptions for the various Shaker bases are as follows:

428: A 428 Shaker base (shown below) is 18.83" in diameter and 5.50" tall. It has 3 "L" brackets welded to the outside edge with a stud sticking up from each bracket that the Shaker intermediate plate attaches to.

390HP: A 390 Shaker base is 18.83" in diameter and 5.82" tall. The Ford service part number is C9OZ-9600-J and the casting number is C9ZF-9600-J.

351C: A 351C Shaker base is 18.83" in diameter and 6.25" tall. It has a lip that runs around the entire base and has 3 studs sticking up from the lid. The 351C has a provision for a breather filter to attach to the inside of the air cleaner base. A hose runs from this breather to the oil cap.

351W: A 351W Shaker base (shown below) is 18.83" in diameter and 6.14" tall. It has a lip that runs around the entire base and has 3 studs sticking up from the lid. The 351W has a metal or plastic elbow sticking out the front of the air cleaner base. A hose runs from this breather to the oil cap.

BOSS 302: A BOSS 302 Shaker base (shown below) is 18.83" in diameter and 5.50" tall. It has a lip that sticks out the front edge about 1 1/4" and tapers down to no lip on the sides. The BOSS 302 has a plastic elbow sticking out the front of the air cleaner base. A hose runs from this breather to the oil cap.

The Shaker hood scoop is adjustable by three pan head screws that attach the scoop to the intermediate plate. This will allow adjustment of the scoop. Note that other Shaker bases will work (although not as well) on the BOSS 302. A 351W Shaker assembly and an assembly from a Torino will work on the BOSS 302.
