They certainly can, all you have to do is make sure that you pulled the donor engine from one that was already stick shift, so the pilot is drilled out. Otherwise you could take the crank to machine shop and have them drill the pilot for you. Everything else bolts together with LA parts. Once again though, make sure that you use the flywheel waited for the Magnum engine unless you are going to take the rotating assembly to the machine shop and have it neutral balanced like a 318, if you do get it internally balanced then you can run a neutral balance flywheel and harmonic balancer
