I don't know those specially, but my guess would be they are scat or k1, or come from the same foundry as one of them. Alot of people don't realize most of the "name brand" stuff all comes from the same foundry, and just gets machined or boxed differently. For what it's worth, a stock rod is good for well over 400hp. I would throw some good rod bolts in stockers and let it roll.
