Can anyone tell me what linkage will work with an original 54 Merc intake and 4 barrel Holley Teapot on a 54 Ford 239 that is originally a 2 barrel? It has been suggested by a friend that the '56 Ford 4 barrel linkage will basically fit to the pedal and kickdown rods, but I don't know...all I do know is that the linkage on my 239 2 barrel doesn't look even close to being usable on the 4 barrel intake and carb.
