so i want to put a 5.9 magnum in this dart using all the electornics fuel injection system.only thing is i dont want to cut up fabricate stuff to put a 518 (4 speed auto )in it.so can i notch the old school 727 bell housing mount the crank sensor and use the magnum flex plate .pretty sure i can do this but how accurate would i need to be on location of crank sensor. this is real budget here so is main reason not just running manifold and carb dont have either
