66 Dart GT HT Whatsitgonnabe?

Mornin' Matt!

I think you're right. Orange would probably pop even more but I don't feel good about using the color that was only ever used for hemi and big block (and possibly some hi-po small blocks, can't remember). Like you said, red is what would've been in there and in fact the original 273 was red.

This is what I'm leaning towards right now then: Petty blue or Polestar blue with a Mopar red engine.

I won't be painting the whole thing like they did in the plant but rather keep the different parts separated color wise. Heads, valve covers, maybe water pump, pulleys and intake of course. I think that looks better. Probably go for a cast iron grey on the heads and water pump, maybe black oil pan and valve covers and matte black pulleys. Brackets either bare metal or perhaps black.
