I've got a 73 fj40 in good condition with the pto winch. all the gages work and lites. has never been repainted. front and rear heaters work plus windshield wiper and spray.

she has a 350 chevy engine with a high rise manifold and 4 barrel carb. she runs sweet but tops at about 55 mph. she has a 3 speed transmission on the floor. except for the engine i think she is pretty stock. no rust in the rear wheel wells, 3 panel rear doors.

question: what can be done to make her freeway worthy, 65 mph. without whining her out.
