Well my hillbilly friend down south only has some printouts from the runs no electronic files. I'll scan the printouts when I get them.
I couldn't make it to the run so all I have is what he wrote me.
Ran a baseline on the gas carbs first then switched to E85.
Highlights
10 inches of vacuum, and the good gas, and made 641 TQ at 4900, and 700.7 HP at 6400. Made a bunch of 690 somethings across the top on hp, and a bunch of 630+ torque numbers from around 4000 up to 5200. I did not touch it from the last pull at Jay's, other than to relash the valves, add the plate under the plenum, and seal the vacuum.
The 850 gas carb made 635 TQ and 687 HP. It was a tad fat. I didn't want to waste too much time, but we figured a jet change would have put it right there on torque, and maybe 5 hp down up top versus the Dominator. It was definitely smoother, and would race better.
The E85 was smaller than the gas 4150..........1.590 venturi vs. 1.500. It was better than the Dom below 4000 rpm,and equaled it up to 5800. Peak torque was 642 at 4900, and power peaked at 698 at 6300. It was 10 better on torque at 3500 rpm. We couldn't pull it any lower without doing a bunch of re-adjusting on the brake, but we could tell the small carb E85 is MUCH better below 3K.
