Tom,
As another comparison, here is my recent dyno chart. 82SC 3.0 liter, 9.8:1 CR JE's, single plugged with Elgin SC330 cams, SSI's and Dansk sport exhaust. The early 80's intake ports and runners were opened up to 36mm. It's interesting to see the max torque numbers and curve are fairly identical and the HP curves are also VERY close. I think this is also an interesting comparison between 964 and SC330 cams.
Your worries were the same as mine...the CIS would not be able to deliver enough fuel to keep the AFR in safe place. Our AFR curves are also quite similar. I'm in the process of smoothing and leaning out the AFR to Steve's recommended 13.2. See enlarged AFR chart below.
BTW: My max advance at Dyno time was close to 38 BTDC (scary). After I brought it back down to stock, there was a noticeable performance decrease.
Keep us posted, this is good stuff.....
