Quite right, this is the little-known 901/30 2,0 liter with 39/35 valves and 32mm ports. . . with 46IDA webers!
My own saga, a long one, detailed here:
Suggestions for warmed over 2.0 901/05?
After thinking about it my compromise between originality and modern performance is 81x66, 9.5:1 JEs, Dougherty Cams, stock 40IDA and all the other invisible updates. I'm hoping for 150 HP, but the torque curve is what I really can't wait to see.
