Q: I need a set of Chevy small block motor mounts for my 1969 Camaro. I’ve been told there are two sizes available. How do I determine which size is correct?

A: In the early years, Chevy used two different motor mounts. The “short and wide” version measures 2⅝ inches between the ears, and 1¾ inches from the engine mount surface to the center of the mounting-bolt hole. The “tall and narrow” mount measures 2⅜ inches between the mount ears, and 2 3/16 inches from the engine mount surface to the center of mounting-bolt hole. Simply measure your old mounts to choose the correct replacement. If you don’t have the old mounts, measure the width of the chassis frame stands. Remember, proper engine angle and header fitment depend on choosing the correct mount.
