Danny, what on the 20H case would feed the 3rd port passages on the looper block?
Since 1925, about 150 different racing outboards have been made.
I have posted a photo of a Quincy split case for the 20-H. If you look at the front both cases look the same. My "A" looper case is shown along side the 20-H case. I quess if you give me a number stamp I can make a Quincy clone also. I beleive that someone could make a 20-H case look like a looper case with lots of welding and machining. The old 20-H cases were sand cast and the later were diecast units. The sand cast cases were tighter. I stand by my statement that it would hard to make the engine perform when you don't have the porting to make it correct. Show some photos of the inside to convince us that its the same as a looper case.

Photos are coming,then we can all make up our mine one way or the other
Here is the 20H looper case.
Very intresting crankcase. Seems like it has a bit of work done to it. The case resembles what you would find on a Looper but port sizes are a bit smaller. Thanks for the photo.

Danny,
Thanks for posting the picture.
One of the unique features of the Quincy Looper Engines was the fact a lot of 20-H parts that drivers already had could be used to hold down costs.
A lot of guys were able to build competitive engines at a fraction of the cost of a new Konig or Anzani.
Obviously that is the situation with your engine.
I can state with 99.99999% certainty that your engine did not come from Quincy with that crankcase.
A lot of very good Loopers were assembled at home using parts from stock or modified Mercury engines.
Of course some were built by racers who felt they had a few good ideas of their own to incorporate into a proven engine design.
You have something that probably no one else has!!
Anybody ever heard of a pumper crank for a looper.
