This shirt is so cool! It’s a big tribute to low-buck big-block horsepower featuring artwork of the original Mopar 440 that’s currently in the General Mayhem ‘68 Dodge Charger.

Motorhomes have long been giving up their big-blocks for cheap muscle car power, and the current Mayhem engine shows how you can hope them up just a little bit for massive fun. I stepped up the compression to 10.5:1, added a Schneider 242/242 hydraulic roller cam, and used the cheapest aluminum heads from 440 Source. Result: 535 horsepower and massive burnouts. This is the best basic street-going 440 I’ve had.

Get down with 440 engine love with this super soft, 100% cotton, made-in-USA t-shirt! I’m sure you’ll love it.
