    If you mean 901-30 it's listed in Bruce Anderson's book as 1967-1968 911 rally, Weber 46 IDA carbs, 80 x 66, 39- 35 intake / exhaust valves, 32mm ports, std. S cams, 9.8 CR, 150 hp.

    Thanks Ed
    yes, I did mean 901/30
    Were the Carbs really 46's?
    Now that I have the right designation - can anyone else help?
    Thanks again
