Gol darn it Steve - there's a problem in River City.
Your thread title says K301. The Flywheel Shroud you painted looks to be for a K301AQS (electric starter engine) since it has that expanded area for a bendix starter gear. I don't think it will work with a Starter/Generator (S/G) if that's what you're planning.
Your flywheel doesn't have the ring gear on it so I just don't know what starting method (Starter/Generator or Bendix Starter) you're planning to use.
Ooh, and your oil pan is not an IH Cub Cadet version. If you try to use it in a Cub Cadet I believe you'll discover that dished pan is right where the frame cross member is for the front axle. Here's a pic of a standard dished (deep sump) pan for an IHCC unit. This dished pan sits right up next to the frame cross member when the engine is installed. Your pan has the dish in the middle which is why it won't work.
