3.9L V6 Swap?
Nice! I had a '92 Dakota 3.9 and loved it. Good power, great mpg. I like the look of the fit in your Valiant (would be the same in '64 Dart), and yeah, it's different. Plus, I'm past wanting to pull wholeshots, more into a reliable, fun driver I can take up & down the Cali coastline or to Vegas (post covid!) Is your 8 1/4" stock or ??
