What's the ideal aluminum block, for max bore, and mild forced induction? Hello, I am an LSx noob. My question is, which aluminum block will allow the biggest bore, with the most durability for forced induction? I'm talking an OEM pull-out, or crate engine, not an aftermarket block.
What kind of modifications, to an aluminum block, will result in a good safety factor? What is the spectrum of things that can be done?
Is there any weight difference, between the various all-aluminum engines, a small one perhaps?

You should talk to some of the builder/sponsors. From what I understand the ls3 would work the best for a boosted motor. What kind of power are you looking for? You really need to know the level of boost that you want and cubic inches then plan from there.

Aftermarket block RHS, best option.

Not much more than 600whp. I know that probably doesn't require forced induction at all, but I'd like to have a good N/A engine at first, say somewhere in the are of 450-500whp, and once I learn to handle that, or get bored of it, I'd like to have extra room to grow. I don't want to be on the edge of any limits. The feeling I get is that this really wouldn't be a problem at all, that it's not an outrageous goal. The primary goal is extreme durability, at a relatively reasonable budget (lol), at least to start.

Thanks guys!
Edit: So, is there going to be any difference in bore spacing, or wall thickness, between the aluminum blocks, or is it all the same? Is there a truck block which is similar to the LS3 (but isn't technically)?

Always cheaper in the long run to do the build once.

^Agreed
I'd use the LS3 block if I were to build a factory Al block for FI. The LS7 sleeves are notorious for cracking with mild detonation, se keep that block for NA.
If you want AL and big bore, your options are a RHS,Warhawk, or DART billet block.
