Sidehill - the biggest drawback will be more power and probably better acceleration, higher top speed, rear tires will likely wear more and you will not get as good of gas mileage because you will be putting your foot into it more often . . . that and you will wear out your clutch and brakes faster than with the 228, be able to haul bigger loads and generally have too good of time with your old truck. I would not advise the swap. Perhaps you would be best served by avoiding the temptation to put that motor in your truck by sending me the name of the guy with the motor so that I can hold you accountable from time to time. . . grin
