putting a ford 5.0 in a 72 Dart

I say go for it. It’s only mounts, a trans crossmember, and a torsion bar crossmember. Same amount of work to do almost any overdrive trans and a gen 3 hemi. Do it, put turbos on it, make 1200 hp and drive the **** out of it. Who cares what a bunch of purists think that never drive their restored junk.
