It sure is nice when a first time dyno customer comes along, and I was able to help him find over 100 HP on the dyno. A young fellow ( 25 to 30 ) has been running a 408 Windsor for over five years. It ran pretty good, but he wanted more performance. He steps up to new AFR heads,and a bigger solid roller cam. He used to run World sportsman heads that were ported, and a solid flat tappet cam. Any how, I get it running and made a quick sweep to see the jetting. It is real lean. He has run this carb for five years ,and he thinks it is close. I go up TEN jet sizes, and it picks up 80 HORSEPOWER. It is still a little lean.. He was looking at his plugs to get his old jetting. By the way, his plugs were way too cold, probably making him think it was close. Any how , I go up three more sizes ( thirteen sizes all together ) and it picks up another 10 or 11 HP.. Now I give it more timing and it picks up every where. He was hoping to reach 610 -615 and now we were up to 688 HP. This young man shook my hand SO HARD, he almost broke my arm. Needless to say, he think I am God, but I am just Joe Sherman Racing. Pretty cool. Huh ??
