That measures to be 382 cubes. If you maintain the same efficiency as the original D-17 engine at 53 HP, you should have 90 HP. Of course, you give zero information on compression ratio, camshaft grind, or carburetor size.

Compression is good I would hope 190 is at .050 on cam with a bigger carb you should break the PTO at 100hp and who knows if its 20 more or 50 more after that.
