Urah Chad!
Soaking in Simple Green (or Bleach, oven cleaner, etc.) will take the Chrome off.
On my 1:1 scale jeep, the frame, front bumper, and bumerettes were all a low-gloss baked on enamel. Black, of course. Probably nice to do the initial paint in gloss or semi-gloss black, then coat with Future/Flat mix.
Has it got the 308 V-8 engine? Stock it would be a very boring Gunmetal grey (AMC coated their engines in a thick rust retarder) but with any Customizing you'd be safe with a nice Competition Orange on the Block. heads could go alum. or steel, and covers chrome or brushed alum. w/black vanes. Avoid the Chevy blue block syndrome...
