Correctomundo. Continental. Must be junk jugs or they wouldn't be free. Notice it's adjacent to an airport.

Junk for a plane might be fixable for a car.

Are those cylinders and heads as one piece?

How close is mueller?

Looks like 470J series 6 cylinder barrels. 7.7 litres of dependable hp at 2500rpms.
125mm bore with a 101mm stroke. Very dependable motors with rotating exhaust valves. Those motors are long at 3 feet in length. Only drawback is they use a narrow rpm band of about 2400-2600 optimized for reliability. Rebuild every 2000 hours of run time.

I use a rule of thumb that MOST normally aspirated passenger car automotive engines make about 1 ft-lb of torque for each cubic inch of displacement. So for 7.7 liters at 60 cubic inches/liter... puts you at 462 ft-lbs...

ignoring the limited power band.. the trans-axle would be a beast....

Might look cool cleaned and polished up as shabby-chic art piece

Yea Rich, they are. If you ever saw a video showing how much those heads move as the power curve changes, you would see why. Jeff's right about the power band. Most AC IC engines won't turn faster than 3300rpm as the propeller tips typically go super sonic over 3000rpm.

Hey, me too. But it was the little brother of yours. An 0-320 E2D. Still have the parts manual.
