I am putting a 0470-50 Pponk engine in my 1953 Cessna 180 and want to order new baffling from Airforms. I believe I can use all of the airforms baffling for the 1956 and newer engines except the two large pieces at the aft side of the engine. For those of you with this setup, can you tell me what you have used?

Thank you

I can't help you with the'53 differences, as I have a '59 (I ended up replacing a lot of mine with Airforms baffles, including the aft outer sections), but I do suggest you get the springs that fit an IO-520 rather the reuse the O-470 springs, as the cylinders seem a little larger, and they were the dicken's to put on.

the pieces between the cylinders are different...

Curses!

I would call Steve and see what he says, recommends.

Steve has been very helpful but was unsure of which individual part numbers I needed vs. what I could reuse. Airforms responded to me but their response was that they didn't know what would work because of potential cowling changes between the 1956 and 53 airplanes.

What specifically is your concern about the baffling of a 56 and later working on your 53? If it helps the upper cowling part number is the same from serial number 30,000 to 50,661, (minus the nose cap) essentially 1953 unti the end of production in 1959. So the shape of cowling through those years will be the same. It should work just fine if clearance was the issue.

What he ^^^ said.....

A '53 with a stock cowl, Pponkd, and Airforms baffling will look exactly like this... Keep it light, fly it right, and it will go almost everywhere a supercub will go, and get there almost as fast as a bonanza... tough combination to beat



Take care, Rob

Thanks guys- I will press forward with buying new baffling.
