Sorry for a request that pertains to a twin, but does anyone have any intake manifolds (carb to engine) lying around for a 72 350 twin? They are still available from Honda, but I 'll be damned if I will pay 80$ for them. While I was doing 350F projects, I saw them numerous times on e-bay. Now that I am getting finished with the F., I need them for the twin and I can't find them. There is one on e-bay now, but the measurements don't jive with mine. I only need one, and obviously, they can't have cracks in them....Thanks!
