Please correct "Powertrain specs":
It's V8 DOHC, not DOCH
Peak power - 230PS at 8800 rpm
Peak torque - 206Nm at 7000 rpm
And add tested acceleration data:
0-100 kph - 4,9 sec
Top speed - 245 kph
Source - Auto Itaiana, issue 27.02.1969
1000 m - 24,0 sec 214 mph
Top speed 252 kph
Tested weight (with full tank) - 870 kg
Source - Auto, Motor und Sport 20/1969
230 PS was claimed power for road going version, power output of Typo 33 race car was about 260-270 PS. AMuS stated, that it wasn't really clear what exact differences were between Stradale and Corsa engines, so they supposed the real power for most of 33 Stradale was about 240-260 PS.
Anyway, only 18 units of Alfa 33 Stradale were hand built and they all somehow differed from each other, and that perhaps caused the difference in acceleration between AC and magazine tests. AC creators most likely used horsepower number claimed by Alfa Romeo for simulations.
