I've seen many single motor boxes have a hard time cranking really tight motors. Another bad thing with those singles, what happens when they die on the track? Two inexpensive 19T motors are great replacements for the box. A pair of hot modified motors won't do the truck as they don't have the low end grunt.
I think 2 good stock motro 23t/27t is good enough especially they are running at almost double the voltage of their usual application. speed isn't an issue, it is the tourque we want.
