has anyone compiled a list of vacuum hose sizes and lengths for a 74 chieftan 440?
i want to replace all the lines and eliminate the vacuum cruise control.

i just measured out 67 lines today from the master cylinder and they are 1/4", we have a 440 as well but i dont think the engine size determines the brake line size, more the vehicle weight overall..

I ordered a MC Raybestos (MC36359) for $45 that matches the old one perfectly, ill put it here for reference only - its a direct fit for our 67- im also redoing the brake lines and cylinders starting front towards rear etc-
