6-700hp. I see some kits for sale, but not so much individual cranks. Aside from Eagle and Bryant that's really all I've seen, so was curious what other members are using. Maybe the question should be which cranks or rotating assembly parts shouldn't I use. A lot of members signatures will say forged bottom end, but nothing specific.
All of them work well. Have not heard any negatives. At that power level I'd def go with a forged rotating assembly. Steel crank, rods and some good Pistons. Can't go wrong with any of these supporting venders. The cranks are also available internal or external balance.
