I know it's a longshot, don't even know if they're available, but does anyone know if a tunnel ram for a 241/270 Super Red Ram Is made ???
I don't think a new manifold has been designed for them since 1954. Edmonds, Offy, and Eldebrock made some but date to the day. I have some flanges and some tubes to make a short single plane one.
Langy--nope, no tunnel rams, a log ram maybe With your skills; you might look under your welding table.
