OS 61 SF with Muffler

I have for sale one OS 61 SF motor with muffler for sale. It has a very minor bit of rash on the front of the head. Was mounted inverted in a P51 and the plane nosed over a time or two on the taxi way. The engine was not crashed, it just scraped the front of the fins on the head. Very minor damage. Otherwise this motor is in excellent shape with great compression and smooth bearings. I would like $85 shipped for this motor.

Is that a ringed or ABC engine?

This allows more gas to enter and therefore ensuring there is enough supply of fuel
I have always used flowmasters on my trucks, they have served me well.
