Get a 5.3 aluminum block and sleeve that. It and the LS2 block are the strongest factory blocks. Ray Litz bought a new 5.3 from GM and sent it to ERL and runs 7.40's with it.

You can pick up 5.3 alum blocks for cheap.

I think he is needing a GenIV block, being that he has a C6Z

If he is just going for a <600rwhp n/a build I don't see any need to mess with sleeving anything. Just buy a factory ls7 block and build it.

I don't believe that is correct. I thought the L33 was a Gen III 5.3L block and the LC9 is the 5.3L Gen IV aluminum block.

Can someone else chime in to verify?

It depends on what heads cam and intake you run along with compression. Or are you asking how much hp is the block good for after sleeving?

You are correct but...

LM4= Gen III 5.3L Aluminum block Version of the LM7
L33= Gen III 5.3L Aluminum block
LH6= Gen IV 5.3L Aluminum block
LC9= Gen IV 5.3L Aluminum block Flex fuel version of LH6

In what ways are the LH6 and LC9 blocks different?

Thanks!

As stated, sleeved blocks can handle a ton of power. I don't see you making anywhere near 600rwhp with Katechs Torquer 116.

What are the advantages/disadvantages of wet or dry sleeves??

Another Q. What is the largest safe bore to go to ,say, if I was sleeving an LS2 block for NA purposes.
