I'll stick with my O-360 Lycoming!After a complete engine overhaul with insert bearings, Falluca insert rods, Egge pistons, and GM rings, the engine runs well and this Pietenpol Aircamper only needs the wings installed to fly again.
This one will cruise easily at 70! More later....

Gar, Very nice job, have you flown it in the past with the sick engine? I have read quite a bit about the Model T powered Pietenpol but not much about the A. They were of course quite concerned with making the T lighter even lightening the block but it only had half the HP.
What kind of air speed can you get w/an A powered model? I remember some comic mentioning that in the T power version you did not need an air speed indicator as a calender would do fine.
My profession is rebuilding antique engines and vintage racing engines. From my experience you may want to think about using forged pistons for safety purposes.
It would be interesting to use a forged piston but I don't know of a source.

This is an update regarding the Pioneer Airport. The EAA museum and the Pioneer Airport is still open during the MARC meet. Pay admission at the Museum. The MARC meet registration includes the admission if you attend the meet. Gar, we would love to see your plane at the meet.Don, I would enjoy that but, since my wife can't drive, I have no way to get both the airplane and our antigue Bowlus camping trailer to OSH. A number of local midwest Pietenpol owners have been talking about flying their Model A powered airplanes to the meet but nobody has committed as far as I know.
To do that, it would be best if the airplanes could use Pioneer Airport. It probably will be closed for the week.

Prop noise and airflow noise make quite a din. Mufflers rob a little bit of power which can make the difference between life and death in an already underpowered plane. Even mufffled, most small planes make an enormous racket in the cockpit. The benefit of using a muffler does not outweigh the cost in power, even though it isn't that much. I used to own a 1955 Piper Apache with twin Lycoming O- 320s which dumped the exhaust into openended sheet metal cylinders call augmentor tubes. I could shake the foundations of any house I buzzed if I put the props full forward and firewalled the throttles as I flew over. The engine on my 1965 Cherokee 180 is mufflered, but I still can't hear anybody talk in the cabin over the prop and airstream noise. Any plane powered by a Ford T or A engine is inherently under powered and very noisy anyways. It wouldn't make much difference sound level wise by putting a muffler on it and it sure would reduce the power available to the pilot.Maybe a stupid question but why don't small aircraft use mufflers? It sure would make them more comfortable to fly.
