Stock rods suck for high horsepower applications. I really really need to put up a picture of stock rods next to the ones Beau sells (or other vendors sell).
Beau does use stock rods at the shop though. They help to fill up the garbage can, but that is about it.....
You NA guys will usually have to do EVERYTHING (ported head, cams, full exhaust, injectors, etc) before you have to worry about the stock rods.
That is for a good stock engine. Many people have blown them with hardly any mods, some people make well over 250 wheel hp boosted on the stock block.
