Using a cam/running compression calculator, you should have about 200 pounds cranking compression if the cam is set at 104 degrees. That will run on 93 octane, or should. The dual plane might very well be a better choice here as well, as most don't loose ground to a single plane intake till after 5000 rpm. Remember that a LOT of time is required to get past 5000 rpm after the launch, and on each gear change. That is why a real loose converter is needed for a single plane.
