LS3 block vs LSA block

As I'm getting ready to build a short block, I had a thought. Would there be any benefit if I was to use a LSA block. Will it handle more strength? I'm researching it but I can't seem to find a lot of info on this topic. Any help would be appreciated.

LS3 is fine. Make sure you have a nice set of aftermarket heads.

LSA has piston oil squirters and might be a tad stronger than a LS3, other than that I don't see much more of a benefit.

If you get a decent deal on a LSA Block go for it, that's what I did.

I am making over 1K to the wheels with the stock LS3 block with turbos. It may be on borrowed time but isn't showing any signs of it so far.

I believe you are using a Ysi and I made over 1k with it as well. A centri will typically be easier on parts than a turbo because of the way it builds boost with RPM.

I second toasta - if you can get an LSA block on the cheap go with it. Otherwise, you will be fine with an LS3 block.

Stock crank and block. Forged rods and pistons.

Centris are easier on the block per se, but they are harder on the crank. If I was going run a centri I'd spend the money on a forged crank.

The LSA block is reinforced for boost according to GM, after physically examining and building several of both the main difference is the oil squirters. That being said though they are an additional source of cooling for the pistons Which on a boosted application is definitely helpful.
As stated, if you can get an LSA block for the right price go for it, but properly built either one will be fine. We have done both between 800-1100 hp with no issues. The most important parts that are overlooked that cause failures on big H.P. Boost builds is the hardware used when assembling, don't skimp on your gaskets either.

I threw the LSA out there because I was thinking of a different route. We know what applications that the LSA is used in, such as the CTS-V, ZL1, ZR1, but I was not sure what the differences were. If was able to handle boost better or what. TSP offers the LSA block for an extra $1K, but after much deliberation the end result is to go with a LSX block so I can get full use out of the 6-bolt heads that I already have.

Great decision, the LSX block is one tough cookie.

I hope. It was a choice between doing a 408 and 427. I went with the 427, I'm just not too knowledgeable about how the LSX427 holds up to boost compared to a factory 7.0

I wouldn't hesitate throwing 30lbs at a LSx block... Oh wait yes we're about to throw 35psi at one

The LS7 block is the weakpoint because of the core shift that we have seen without a girdle.

What about the cylinder walls being too thin in the LS7?

I think a 427 ls7 and a 427 lsx are totally different. Not just one is aluminum one is iron.
