Balancing an engine

I'm not sayin balancing ain't important here...so don't pile on. But yall tell all that "you gotta balance it" stuff to them Saturday night dirt track boys. LOL

I'm not in a dirt track area up here, but I can tell you the winners on the loacl short tracks ALL have special balancing done on the primary and backup engines. The shop I use has had multiple track championship engines for years. It's almost 50% of his business. If they aren't spending on it, they are missing out on some free power, and a little jump off the corners.
