I dout will ever hit these power levels but you never know and am mosty just curious.

I am currently targeting about 1000rwhp max on my build but it might go to say 1200rwhp at some point in future.

So what is the highest rwhp put thru a basically stock block 6.0 iron. By stock I mean built crank,crods and pistons but no concrete or whatever fill and no funny stuff aside from maybe arp main studs.

I realize LSX block is good idea on these big power builds. As said doubt would ever run the high number above but am curious how much power people have put thru the 6.0 iron. After all the LSX is pretty much just been out for last year or so.

iirc veee8 is running like 1000HP thru his 370...

I pushed 1213RWHP thru a production aluminum block, so an iron should be just as capable

X2, Harlan went low 8's with an LS1 aluminum block, so iron should be much more capable. I would think the 4 bolt heads would push water before the block itself is an issue.

I'm not sure if you consider doweled stock mains "funny stuff" ?

I have read many high HP builders recommend these before the 1k RWHP.

I'm curious why most don't bother with this?

But, as said above, a few here have posted stock blocks at that range. I like to know the consequences tho. Ok, so they made the number, how long before cap walk really is too pronounced that it will cause issues and an engine tear down?

If I recall properly, to avoid issues.....750+ is where it is recommended...
Thats all I can think of for the block other than block deck thickness/stiffness affecting head seal at the 1k range.....again, all based on what I have read here.

definately pin the caps at that level...mine weren't pinned and the caps were walking upon teardown, but bearings were ok looking

TrakDay's hovering around 1k with his GTO, IIRC.

Last year with my 6.0L iron block (Bored/stroked to 408), no fill, with ARP head bolts (not studs), no girdle = 1003 rwhp.
