"Allen Millyard has done it again, this time taking two cylinders from a Pratt and Whitney 1340 radial and making himself a 5 liter V-Twin, the "Flying Millyard.
The original P&W 1340 radial was a nine cylinder, 1,344 cubic inch, 22 liter engine. The new 5 liter engine is intended for a Flying Merkel type board track racer, a BIG board track racer I imagine. This should impress the boys down at the Ace Cafe, don’t you think?”
