Gas Monkey garage Hemi swap

Right?

And hey, that's 485 hp. :evil3:

Don't get me wrong, I love the 340 in my Duster. And I wouldn't swap it for a modern engine. Not because they're made in Mexico (hey weren't a ton of these cars built in Windsor? That's Canada! Commie bastards!), but because I don't want to deal with all of the electronics. I like simple. But yeah, that new Hemi probably puts down 50-60 hp more than my 340, and gets about 2x the gas mileage. Ouch.

Yep, efficiency is a magical thing. The 5.7 in my car probably doubles the horsepower of the 318 that was in it when I bought it and is starting to get better gas mileage too as I get the tune dialed in. For the longest time it didn't matter what I did, my car would get 16 mpg. New rear end on the 318? 16 mpg. Hemi swap with carb? 16 mpg. Fuel injection swap? 16 mpg. 6 speed swap? 16 mpg. Cleaned up tune? 18-20 finally. Guessing I can squeeze some more, but without a dyno to do tuning on it's hard to really dial in the different load conditions steady state.
