Trust me when i say this engine will give you guys some business. The people i race with have to see to believe. My engines and some of the ones i build for a few other people are respectable runners and draw praise from racers. Neal's B5 will be alot more brutal than what i usually run. Let's hope i can adjust my throttle finger so it's competetive. I've already seen them tear the glue loose on tires and that one didn't even have a good performing pipe on it. Also seen 1st hand how OS plugs fail in them. Werks plugs it is.
