The basic concept with this engine was to make comparable HP to the P6 cam, but with better low-end torque. This was achieved by increasing the cam lift while maintaining the P6 like duration. The usual modifications were made to the cylinder head for better breathing and a full Tubi exhaust was installed including the Euro-spec headers. A very special “Comp-type” air box with snorkle was fabricated for this engine as well. The best dyno runs were made with the “Comp” air box in place. The stock air box won’t go over 400HP.
