Cofap was (maybe still is) a major aftermarket supplier of VW parts, but I didn't realize they made cams or gear, so you see how long it's been since I paid attention. If your engine is really a 2180, that pegs it as a Type 1 or Type 3. Like Orma said, those two engines are all but identical except for a few holes, and almost perfectly interchangeable except for some engine mount holes. As was mentioned early in this thread, it's dead simple to identify one of these, as the exhausts run out the front and back of the engine, parallel to the ground. These are the typical Beetle/Ghia engines up through 1978, and used in buses until about 1970 or so. Then the buses (and 411s and 412 stationwagons) went to the Type 2 (if used in a bus) and Type 4 (if used in a 411 or 412). The easiest way to identify one of these is the exhaust pipes run out the BOTTOM of the engine (as was mentioned before). There's a photo of a Type 2 engine (or maybe it's a Type 4, they are cousins as close as the Type 1/3) located at the bottom of http://home.hiwaay.net/~langford/kvw.html . Notice you can't see any exhaust ports, as they are located on the bottom of the head, not the front and back. Basically, parts for Type 1/3s are interchangeable (as long as you have the right displacement, within the same year (and almost for the life of the engine), and Type 2/4 engines are the same way. The engine code is what most folks use to determine exactly what an engine came out of, not the part number. Any VW book worth anything should have the engine codes in it. Tell us what number is stamped on the top of the case and it'll go a long way toward telling us what you have, but the aftermarket parts means that all bets are off in displacement. But the 91.93 stamped on the pistons almost certainly means it's a 2180 Type 1 (or 3) engine with 92 mm pistons and cylinders. When referring to it it with suppliers, just call it a Type 1. The Type 3 thing makes no difference for aircraft specifications, as it just means you have some extra engine mount holes drilled in the front of the case.
