1972 Dart LS swap

I have a magnum swapped duster (finished) and a 5.7 LS swapped satellite project. For 400 hp range the magnum is just as good and dare I say cheaper than the LS. The reasons I chose LS on the satellite were the following: all aluminum engine is considerably lighter and I really wanted a seamless fuel injection system that wouldn’t break the bank. The only magnum swap harnesses I could find were $800+dollars, then you need to spend another $900 on a good mpfi intake setup. That and I’m much less informed about trying to tune the stock dodge computer. Both good swaps IMO.
