quick question..i have a pontiac sunfire that is totaled but a good engine...would swapping that engine into the monty possible? has it been done? i know many go for the turbo and v6 swap but figured what the heck have a good engine and if possible why not. By the way replace the thermostat and filled the radiator up. change the temp sensor and radiator cap. ran the monty and didnt over heat. checked the oil and found no signs of water.
