Is good to over 300whp with a good tune. A lot of guys blow up with some bad tunes at that power level. We have what I believe are AEB or similar rods, which should hold a lot more. The pistons are bulletproof at 4-500hp IMHO, along with the crank.

however, it depends on how you get that 400. If it's from a small turbo running tons of boost and heat.. then maybe not so safe. Larger turbo running lower pressure, but the same temp corrected CFM... follow?
