Iron block suggestions
I am thinking of making some changes to the 6.0 that I have. I am wondering how well the stock bottom end will hold up to sustained 5500-6500 rpm range. I know that is fairly broad but its just a starting point. What kind of cam/ head setup would work to get the engine in the 500-550 crank hp range. How well will the stock water pump hold up under these conditions. I am thinking of putting the engine in a boat for racing, and want to make sure it can handle the loads.

my 500 hp is super tame till you get on it then the 490ftlbs is what makes it WILD
as for the high rpm for long times as long as bearings clearances are good and your OIL SYSTEM is up to the job and doesnt suck the pan dry IE NO HIGH FLOW PUMPS HIGH VOLUME ANY OF THAT. my 402 has a stock pump and works just fine.
i told my dad not to use a high volume pump in his 383 LT4 vette. guess what happened when i hit 150mph and held it for only 3miles looked down and saw no oil pressure but it was too late. POPed a rod out the block.

I am not after rwhp, just crank hp. This is for a boat application. I am thinking that with the heads ported and milled, and a decent cam, I might should be able to get the 500 hp mark without too much trouble.
Any idea how good the stock rod bolts are?

Thats what I was thinking. Since this will stay n/a I don't see any reason to forge the bottom end. If I mill the 317 heads and get a mild port job on them, which cam is going to work well in this rpm range? I don't want to get too big of cam that will loose all of its low rpm power becuase I will never be able to get the boat on plane.
