Help choosing a v8 for my dart

Magnum advantages over LA

superior pan and valve cover gaskets
hypereutetic pistons
heads as good as any 340 stock ones
less rotation mass
better factory machining
metric rings
etc
I don't know too many people if not nobody that actually runs an original LA based engine that hasn't been overhauled so again everything you are taking your stand on is pointless and one of my big reasons why you will never see that trash in my cars is that it reminds me of the modern era when Governments instead of Men built automobiles and for that reason alone i'm good with leaving the Magnum engines in the junkyards.
