Well I'm back after another pull scheduled for Friday afternoon. Brought my heat gun with me. During engine warmup, discovered cylinder 7 only at about 387 *F. All others are in excess of 1000. Heat gun only goes to 1000. Turns out the spark plug wire was burned about in half by the headers. This was through heat sleave I have in place. Pull results are as follows.
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!
