Did I read right that a single port is more torquey then a twin port but not as powerful?

Hi,
Think i read that somewhere too. IIRC, the SP has a smaller carb, the twin port has a 34 PICT3. You can fit the larger carb on the smaller manifold, with a adaptor.
Below the alt stand should be the engine number

The B code is single port, AD, AE, AS are twin port.
Mine is a AE type engine, which is a Beetle engine, USA only, 71 model year, twin port.
Cheers,
Alistair

Factory output graphs for SP and TP 1600 engines. I've also heard an SP is the torquer of the 2 but these graphs say otherwise. Not only does the TP have slightly more power, but it appears to have more torque through the rev range.
Sorry about the huge pics. I stole them from acsa.
