I went with the Solex cam because it was recommended by JB Racing and because I found some dyno numbers that showed a high, flat torque curve, which I wanted for a street engine. I am completely satisfied with the outcome, but two others you may want to consider for a similar application are the mod s (DC-40) and the mod Solex (DC-30).

I don't know which is true as I have no T ports on hand to measure but I've had multiple people tell me Brucey's book contains typo's and inaccuracies and on this thread it appears to claim 30mm ports on the T:

I do have a 911T so maybe one day I'll have a chance to measure them and find out for sure. Either way, I'm glad your engine gave you a good outcome.
