James,
The engine was a bone stock '82 USA 911SC engine, other than the following:
Recurved distributor (and converted to full mechanical advance)
SSI exhaust with M&K 2 in/2 out muffler
20/21 cams
PMO 40mm carbs with 34mm chokes (venturis)
Engine otherwise rebuilt stock.
Hope the visors worked out for you, and sorry about your loss (funeral). I've had my son on a full-time motocross training program (5 days at the race track per week.... every week) for quite a while now, and have not had much time for anything else. And it looks like this schedule will continue for the next year at a minimum (which is why I'm selling my 911's BTW). Lots of driving... and lots of stress.

This is great thing to see on your dyno..... the effects of a 20/21 cam. My torque curve is very similar with 150 ft lbs at 2500 and a flat peak at 4500-5000. The HP curve is quite different though. The stock SC cam in my car generates 184 ft lbs at 4400 but only 179 RWHP at 5800. I lose thrust fast after 5500. I'm thinking about the 20/21 or DRC DC20 profile. I think my power figures would be pretty close to what I see from yours.

old thread I realize. Which PMO's for a 3.0 with SSI exhaust, euro pistons and 964 cams?
