From the 1955 Wayne Manufacturing Catalog comes the prototype for a DOHC conversion for a 270″ and 302″ Chevy-GMC. It consisted of three sets of castings. As a cost reducer the cams are set up to be chain driven. Dual plugs and a penthouse combustion chamber designwill be featured. Plans call for the fully assembled head, front castings, special pistons and fuel injection to run about $1,000.
