Arron , I think Ken Kitchen was working on a 300 six. I went and took a 235 from a Chevrolet and then modified the intake and exaust to work on the opposite side . See, the physical size of those blocks were nearly identical in scale . As to building the valve cover , I took a block of EverGreen strip and made a valve cover . I have the factory shop manuals going back to 1957 on the C O E's let me know what exactly you need as I can copy out and mail the stuff to you . I used to drive a 72 Ford C-600 with a Catipiliar engine in it so the differences are minimal .
Sorry I didn't have the aircleaner off , if nessesary I can reshoot the motor and show it to you that way . Ed Shaver
