Why a type 1 engine? The guy I met on vacation said a re-ground 912 crankshaft was $2800. The 912 engine uses a 82.5mm bore and a 74mm stroke to the VW's 85.5mm x 69mm. IIRC, he said Porsche decreased the size of the journals to make up the difference, and as a result the crank was the engine's Achilles heel.
The type 1 engine he used was a stock 1600 - don't remember if it was a single or dual carb setup. He had the optional 5-speed and it had no problem accelerating around the twisting mountain roads we were on. He never really got down on it, or revved it very high but from the passenger seat it felt like it was pulling pretty good. As well as a 912 engine? Doubtful, but considering it was missing ~40hp it was holding it's own.
PS - I've got a copy of a Car & Driver (October 1965) with a roadtest of a 912 5-spd. Engine output was 102bhp @ 5800rpm and 91lbs/ft @ 3500rpm.
