It is a little hard to put a value on a Original Max wedge engine ,it depends how Complete it is .Things like Original Oil pans ,Air cleaners ,Carbs ,Exhaust manifolds ,Crank ,water pump ,alternator pulleys ,All play a big part in the value of the engine ,Some of those parts are Impossible to find ,but reproduction are available for some .Also Original Engine Blocks are very scarce ,But if the Engine you have is Complete ,It is a Very rare Item and Valuable ,Good luck with your Car .I love 63 Plymouth Soft tops ,Especially Sport Furys .

63SFC your car is one of very few I would say that came with that many options ,on the trim tag it is a S2 car which means it was sold before it was built (special ordered).Built on or around December 28 ,361 car automatic ,Heater ,AC,Power windows ,power steering ,power brakes ,White body ,Red and white interior ,White top ,A Fancy Sport Fury ,A lot of the cars I have run across thru the years never had many options .To get a total run down on your cars trim tag I would suggest getting in touch with the Chrysler Historical and have them pull the IBM build card for your car ,They charge a fee but it will give you some good Information ,on that rare Plymouth .
