If you are going run a set of Mercury 2.5 Liter cylinder heads, you've got to make sure you measure the combustion chambers correctly for fuel type, octane, timing, jetting, and of course, race rules requiring certain compression or pocket size.


The Super CCing Plate is made of high-quality, clear acrylic material that measures ¼” thick with precision-cut flat surfaces and smooth edges for the closest head combustion chamber measurement each time. These are made in the USA to be durable and long-lasting.


Check the video in the gallery above for a quick example.


Includes one (1) Super CCing Plate and one (1) small Buckshot Racing #77 decal.
