Think your LS engine is superior to dinosaur-era V8s? Then this shirt is you!

When I released a shirt with the classic firing order of 1-8-4-3-6-5-7-2, the LS guys went nuts claiming that 1-8-7-2-6-5-4-3 was far superior. Now they can put their T-shirt where their mouth is. Same for those few of you with 4/7 and 3/2 swaps on the camshaft of your old-school musclecar. And ya know what? The Ford H.O. and 351 firing order is the same if you renumber the cylinders like it was a Chevy. So Ford did it first.

These T-shirts come in black, are made of soft 100% cotton, and feature the DF logo at the neckline in the back. Made in USA!
