I agree with you "lazylongboarder", 268hp doesn't look much for a 3 litres, but dont forget its only a FLAT4 8valves engine, I think it's very correct, and dont forget it's an injection, no blower or turbo.. and this engine could be driven daily!!!
just to compair,(it's an example) it's 268 hp out of a Flat4 8valves engine and a old E36 3litres M3 give out 286hp of a 6 cylindres 32valves!!!! and that not very old technologie ( 1990 for M3 ), type 4 bloc are on the market since 1969!!
by the way, the engine is already sold....
he is making an upgraded copy at the moment to replace it..
