Those are all awesome cars for sure and I agree with Arne.
I'll take mine. 2150 pounds. 80 less in the ass. Drive it mid rpm's or drive it to 7200. It doesn't care. I do have to admit the 6 makes better music.
The graph at the crank is of another 2.4 liter 993 based 2 cam 4. It doesn't have the worked over heads and titanium valves that's in my car. The heads flow half way between the 993 and the 993 3.8 RS. Dean guesses it's good for maybe another 10 hp. Rear wheel numbers here in Denver adjusted for sea level came to 181hp and 154 torque. At the crank at sea level? Who knows. Maybe 4 to 6 of these in the world at this time. Sorta rare.
Kind of sorry for crashing the party as I don't have a 6 but I do have 2 cams. It's my favorite year of all time for F1 cars, many street cars, etc. 1967. If I had a 6 my vote would go to the 67S. I'm a SWB guy to the bone. Why not the 67R? I also like some torque.
