It kind of depends how serious you are in original. Original would mean no ARP manifold or head bolts, cast iron water pump, stamped - steel pulleys, original (no vacuum advance) Ford distributor or Duraspark unit, standard powermaster starter and alternator, restoration carburetor. Pretty much what I did on my 428 motor except I had ARP bolts used. The stuff is out there - some of it is a little rare and pricey.

I figure a few concessions to originality don't take away from the illusion - even original cars of this sort often have some parts upgraded over time.
