I'm restoring a 1945 F knucklehead. It's all stock, but of course, I couldn't resist putting a hotter cam and high compression pistons in there. I want to keep a Linkert. I have an M-74 and an M-35. I'd like to keep the M-35 (appropriate for that year), even though I know the M-74 will work better. Do you guys think I can keep the M-35 body and put all the M-74 internals in it?
