Server had problems when I tried to view it yesterday. But I just got to look at it. It doesn't say that it is a stock block; it just lists the other parts including custom manifolds, turbos, engine management, etc. It DOES mention use of custom camshaft (specs undisclosed), so it's not a totally stock motor. It could very possibly have a stock bottom end. I found more evidence that the stock RB26DETT can support up to 600HP. Very impressive; so now I can't fairly guesstimate which one is stronger.

At least somebody else posted some evidence to their claims. Thanks for the info; good stuff.

I'm done here. Peace.
