The real deal boys and girls. This is the ultimate from piston power, Old american V8 comes second.

Sounds a little rich on pots 4 and 7 #:-)

[Gasthauz]

It says Griffon in the headline, indicating late Rolls Royce engines. But the smoke from the two opposite pipes - that would give me the jitters.

maritime plane

[detroitiron302]

Rolls Royce aircraft engines.

[junniper3]

Single prop racing airplanes most likely.

What the hell are those engines off of?
