Hey guys-just thinking ahead and since there are probably so many on here that can easily make these #'s or have already have-I figured you would know best. If you where to build a motor with a goal of 1000 rwhp-would you use the 6.0L aluminum block or the iron block-no LSX blocks allowed. No strokers-just a 364 or 370 max. Another thing what about the crank-stock or aftermarket.

Thanks!

Iron for durability. Less core shift and such with extended use. Just my 2cents.

i chose the 6.0 iron block. I have the same goal you do, and i hope i made the right choice. i will be doing a 408 tho.

6litre iron block here.I think the aluminum block will distort under alot of boost.I was told to go with Iron for the durability,so I did.

+1 for Iron if you don't mind the extra 88lbs, that is what I picked for
my build with similar goals.
1000hp is common now with aluminum blocks, but you know things will be moving around
inside an aluminum block at that power.
I am not racing for money, so iron block for me!

For 1000 rwhp, I'd go iron if you are talking about stock blocks. Bob

Filled 364 C.I.D. W2W LS2 here. More than a few have shown what the aluminum can handle. Harlan, Mike Brown come to mind (both low 8 sec. cars). I thought I read Major Spray was an LS2 (7 sec. car)? You can make a good case for iron at the 1000 rwhp level, it surprises me though how many carry the extra weight of iron here that have 500-700 rwhp, I see no reason. The coolest thing about the LS engines and what is making them take over the SBC in street rods and other custom applications is the fact that they are full aluminum. The stock crank is another very stout piece that has shown it can hold at the 1000 rwhp level (we're not running one of those though.

all the cars you mention are not daily drivers using stock type motor mounts.

I know of a 6l iron block that will be going for sale.

I would go iron 6L Arun...The weight is a bit of a pain but the block will handle it better on the street than a half filled alum block
