just thinking out loud!

Whoa, 900 hp?  That's insane!    I don't think there's a cast block in the world that can handle 900 hp. You better contact CN Blocks and ask if they can make a billet one out it titanium, then the block will be up to the job.

i don't understand paul! people on here claim to have run there blocks passed 800-900hp all day long!

if all your thinking about is resale value your in the wrong hobby......

It was just an attempt at humor. In most cases the block will be fine; of course the more power you ask of any engine component the more attention it will need. I don't know the detals of your build and application, and whether or not any part is being used beyond its breaking point is another subject altogether.

Based only on your target hp numbers: if you are talking about a stroker engine then I would recommend the offshore forged crankshaft over the offshore cast one.  And in regards to your using hp power levels as a conclusion that a forged crankshaft would be "overkill," consider that there will always be a stongest component and a weakest component in any engine combination.

100+ drag racing passes out of a "few hundred dollar" crankshaft that (I suspect) is made out of recycled car unibodies and melted down coat hangers is some pretty good usage value.   And most components, new or used, require pre-inspection and adjustment prior to going into a high performance build...at least at the cost levels we're discussing here.
