I have the same engine. It is the one that I have described here on RCU as turning heads whenever it starts. No stock muffler, but a Mac's open front instead. I run an 11x6 prop for exhibition flying (I should have said that I used to...). Yes, the prop is considered to be at the lightest side of the engine prop selection chart. When this thing is pulling around one of my .40 to .50 sized show planes, that are built to withstand the rigors placed upon it by this engine, heads turn. Even after all of this time (30 years), it takes second place to no other engine for the job it has been chosen to do. Simply put, it howls.

I would love to pick up another one. They are scarce.
