Default lq4 Question

Eventually I will be building a stronger motor to handle more power than the 383 I have now. My question is, what all need to be done to the block to handle 1000+rwhp.

You can, it will be stronger then as well and have the large bore. You can only bore these lsx motors so much, especially the aluminum ones.

OK, But most people I see that build the iron blocks do not sleeve them because they already can withstand a beating seems like a lot of extra work and money for the same result to me.. I know you do need to change the sleeves on some of the aluminum blocks of you plan to make a lot of power

Its gonna boil down to what you want to do and how much power. If you want the big bore you have no choice but sleeve it, buy an aftermarket block or get an ls7 block.

I think more information is needed to make an accurate answer.

How do you plan to make this power? Na, you're going to need a lot of expensive parts, and more cubes than a stock iron block can handle and still be reliable.

If you're going with boost or spray, you can get it done with the iron block, forged internals and studs all the way around.

Heres my recommendation. The newer the block the better, the casting process got better along the way. Next have it sonic checked and a good going over. Still think about sleeving it thougb, but if you go that route get an aluminum ls3. More cubes, better block, longer sleeves

Again, studs, main caps, forged assembly, good bearings rings etc, if you can run a girdle support go for it, it wont hurt.
