Great Plains Aircraft Type 4 Long Block Conversion Kits will convert any customer supplied 1700cc or 1800cc Type 4 engine into a 2200cc engine or a 2000cc Type 4 engine into a 2400cc powerhouse. These kits contain all the necessary conversion parts to convert your engine and all machine work is included in the price. You send your case, crank, heads and connecting rods to us and we'll do the necessary machine work and return these parts along with the necessary bearings, etc., for you to complete the assembly of the engine. Type 4 engines can be outfitted with dual ignition, just like the Type 1 engine can. If you are looking for a truly affordable engine conversion package, this could be your answer.

| Force One Prop Hub | Force One Main Bearing | Force One Seal Kit | Main Bearing Set |
| Rod Bearing Set | Cam Bearing Set | Camshaft | Pushrod Tubes |
