I yanked my original 67 273 engine and trans that needed rebuilding and put a 340 in it. If the next owner wants to rebuild it back to stock I have all of the hard to find stuff in storage. The head gaskets are hard to find for 273's. IF you want to rehook up all the a/c stuff you need to stay with the 69 and older timing cover,pullies,water pump,brackets. The compressor is designed to fit the 69 and later water pumps (cast iron),70-up is aluminum and requires different compressor brackets,pullies,alt bracket,radiator,hoses,shroud.
