Wearing this shirt is like having the secret code for gearheads! I started wearing one of these and all of a sudden people who didn’t even recognize me from TV started saying, “hey, firing order—I get it!”

See, 1-8-4-3-6-5-7-2 is the most common firing order for old V8 engines. It’s used for big- and small-block Chevys and Mopars plus Buicks, Pontiacs, AMCs, most Oldsmobiles, and even DeSotos, Packards, and Studebakers. Probably more. It’s the most unifying V8 engine spec on Earth!

I made the 1-8-4-3-6-5-7-2 shirts for fun and for my love of vintage horsepower, but they’ve triggered so much conversation that now they’re available for sale! Nab one. As usual, this DF t-shirt is black, 100% cotton, and made in the USA.
