The early 2300 had a carb intake that fit up close to the engine and might fit, the late model Ranger 2300/2500 with intake curving over the valve cover just
will, but the 2.3L turbo won't due to where the turbo is mounted. The 60° V-6s fit, but you have to use some rather expensive "hot rod" accessory brackets to pull them in, or make your own. The factory brackets put everything out beside the motor where there's no room under the hood in the little Rambler. That's in the 58-63 Americans (same under the hood except for the firewall/heater). Almost anything will fit in the 64-69 models -- even big blocks (though they are tight).
