What is the biggest LSX block they make? Because I want to build an LSX with a big turbo set-up?

 

i believe there is a 454 lsx, might be bigger

 

the lsx bare block is capable of 482cid...and accepts all ls heads cranks and whatnot...but the block its self cost 2grand

 

I believe Dart has a tall deck version LS block thats capable of near 500ci, or was it 600ci LOL, for some reason the number '581' is sticking in my head... if you want big, there you have it.... dont forget to withdraw your lifesavings upon purchase though.

 

518 is the biggest I've heard of. That's with the tall deck version of the block.

 

Most builder suggest not maxing out the LSX block for forced induction. Most suggest 409 or 427 max.
