Most of my stuff is big inch carbed stuff designed to make a lot of torque at low rpm and be consistent as heck all day long in either 8.90 or 9.90 cars.... Just never saw the reason for anything better...Never have broke a 2000!!! I think if I was still circle burning with a sprinter or running Nitrous, Nitro, Blower, or a Turbo and 7,000 RPM or greater I'd step up on the bolts..... I've even gotten away with aluminum rods and lightened cranks in a lightweight car running 9.90's, just gotta check them a lot more often.
