I have the opportunity to get my hands on a 1979 440 from a friend for $200, its a complete running engine but if I get it I plan to go through and rebuild it anyway. But on to the point I was wondering if there are any drawbacks to a later model motor like this one when compared against earlier years? My 1967 dart came with a 273 and I just wanted more power I plan on it being a driver with it making the occasional trip to the drag track to play so anytips would also be appreciated for this build. Ive only dealt with small blocks up to this point so if you couldnt tell Im pretty new to a big block lol. Thanks in advance.
