german, but pics of the motor, it was a 1600cc with stock exhaust internally modified and 46 IDAs, 125 DIN hp on a non c/w crank and 9:1
denzel in Vienna also made square port heads

Some more details in the article which Karl H mentions above:
The Porsche Salzburg type 1 rally engines first started with 1584cc displacement; later 1599cc and achieved up to 125hp. Engine case only received some modifications for a dry sump oiling system. The heads were flycut 1mm (0.040") and reshaped into a semi-hemi combustion chamber which provided 9:1 compression ratio. 40mm intake valve, stock 32mm exhaust. Special D-shaped intake ports to match the intake shapes from the Sauer & Sohn manifolds. Stock fuel pump. Carbs were initially Solex P40II from a Porsche 912; later came Weber 46 IDA from a Porsche 904 which were modified for this engine specifically in Maranello. The muffler was a stock unit but gutted internally, along with stock but gutted pea shooters. A stock camshaft was reground to a "secret grind", made by Porsche Salzburg's engine wizard Paul Schwarz and his son on their home basement camshaft grinding machine. The flywheel was lightened 2 Kg (4.4 lbs) and balanced along with the crankshaft. The pistons were based on stock production units.
The article provides some details on the dry sump oiling system, and suspension modifications.
