Rick-
See my post above. There is no base class listed for the Euro Carrera 3.0 anymore, so you have to consider the car as either a '74-77 911S, with the USA-spec 165 HP, 2.7L 911S engine, or possibly "backdate" it to the '74-75 911 Carrera 2.7, with 175 HP, as the base when calculating points for improvements in H class. Your HP delta would be 39 for the former, or 29 for the latter, so either 9 points or 6 points for the engine.
If you consider it as "backdated", you must compare all the other aspects of the '74-'75 Carrera when assessing further points, including the weight, suspension, trans. gearing, etc.
Also have a #7310923 915/62 non-limited slip on the tranny, is this the 8.31 R&P and the stock tranny or one that came with the ROW 930/10
That appears to be a 1981 ROW 5-speed tranny, so was probably swapped in with the 930/10 engine. R&P is 8:31, and gearing is 11/35, 18/33, 23/29, 26/26, and 28/22, if they have not been changed in the past at some point, which is always a possibility with a race car. I do not have the spec book for the '74-77 911S or the '74/75 911 Carrera, so I can't tell you how that compares to them.
