Ok well I can put a 318 Magnum in it instead and the rebuild the 273 which will have to be next year ... I've actually been thinking about doing that instead the only thing is the 318 is in my truck and put the 440 in my truck the only problem with that is my truck is a 4 speed 4x4 and I wouldn't be able to bolt the 440 and 727 transmission to the transfer case without changing out the rear output shaft and casing and I don't know if that will work with out doing more work on the transmission
