then toyota puts an 8L in a prototype thats been tweaked up to 600ft/lbs, need to slap the engineers that thought it was a good idea.
Remember it's neither a prototype nor was it built by engineers. It was something a builder was given free reign to build, build us something for the show type of thing. If they were to get serious I'm sure they'd step it up, but for a truck built specifically for sema the engine was a good choice.
