318 roller engines best source ? not magnum

I like Magnums.....In 1998-2001 Dodge 1500 4x4s :D

(but I have a hard enough time telling my Local parts stores 5 different vehicles to get a bill of parts for one Dodge Dart Sport)

Magnums have cool cylinder heads, and serpentine belts....and require a special intake manifold like a Vortec Chevy....no Mechanical Fuel Pump Provision....and camshafts cost more for one....

I could go on and on...
