The Great White Brick - '69 Valiant

I'm getting a complete floor pan (minus the front pans) from a donor car at a wrecker in upstate New York. $125 cut from the rear frame rails to the rockers to the back of the front floor pans. It will include part of the rocker panel. This car has serious rot underneath, but everything up above is really nice, that's why we think we should salvage it. I don't know.....it's fun to do too! I'm learning a lot from my buddy Tom who is the main welder.

I've been thinking about engine color, what would be correct for a 318 in this car? Was a 340 optional in a '69 Valiant?
