I don't think you'll have a problem with the bolts--its usually the rod that fails, and that is all relative of course to your tune. That being said, they are cheap insurance.

You should have piston problems before you will break a rod bolt. If your method of boost is decent you will have no problem making well over 400rwhp.

I agree, we've always seen the stock pistons break first. Bob

+1 It would seem the most stress the rod bolts see is the transition from upward motion to downward motion. Thus, rpm's and rod/piston weight would be the issue.
