Welcome to the Team Earl!
I agree with Larry as to upgrading to modern safety standards but I would add a big honking 496 or a 540 BBC under the hood with a 390 horsepower 427 livery on the engine decals and fender insignia. Use a 4L80e transmission and a 12 bolt rear with 3.55 posi inside. 235 up front with 265 tires out back 70 series Goodyear or Michelin radials for rubber. Safe and fun to drive.
I can help you spend your money building an autocross or drag car winner, but I know next to nothing about body work and restoration freatures (as I would rather use Autometer mechanical analog gauges to a NOS stock factory gauge set some gave me for Christmas, but that is just me). I grew up at race tracks, but I worked around show rooms for thirty or so years but only because my best bud was a line mechanic at the dealership. So I don't get excited about a factory restore, I am all about Safely maximizing a cars performance so it can be a street cruiser as well as a menace at the track.
I try not to step on anyone's toes, but at least you know where my opinion lies.
