SO all you did was change carbs and gained 20 hp at 5000. I see the horsepower is still climbing at 5200 on the second pull. You haven't reached maximum horsepower yet. Slap that dyno operator upside the head for me will ya!
Ran carb yesterday with 600 holley and avs. AVS on last two pulls. Holley (first two pulls of the day) had better A/F numbers but room was cooler. Was more interested in pull with my carb this morning in cooler environment.
