This Great tool from MMR is required to properly install 5.0 Coyote Camshafts in your Mustang GT , Boss , F150 or GT350. Unfortunately Ford didnt give us a easy way to rotate the cam to install the sprockets. The Coyote Experts at MMR have made life easier by manufacturing this great tool that can turn the cam from the front or the top to help you align the dowel pins on the sprockets. If you or your engine builder want to build it "right" , then you need one of these! Order now $69.99 : http://www.modularmotorsportsracing...in_page=product_info&cPath=52&products_id=874 WARNING! NEVER Try to turn a coyote camshaft using the camshaft position sensor trigger wheel at the rear of the cam!!! This will bend or break the trigger teeth off and render the cam useless!!
