Enough to handle 350 rwhp?

I've heard that the stock 24#'s are good for close to 350rwhp. some have made it closer to 400rwhp, but I wouldn't chance it.

I'm on stock injectors and my AF ratio looked nearly perfect on my last dyno run at around 12.9/13 to 1, I made 355rwhp. I've never checked the duty cycle on them though, thats the most important factor. I've heard they are good for up to 400 at the motor and I'm just over that. If I was making anywhere near 400rwhp I would definitely want to go with at least 30lb injectors though. You could probably run stock injectors with 400rwhp but I think the duty cylce of them would be to high to be safe.
