Default aluminum 5.3 casting ### Sleeving?

Hello world, who here know casting numbers to the aluminum 5.3 blocks to the ones are sleevable......
I have been told all aluminum 5.3 blocks CAN NOT be sleeved. I need to know what I'm looking at before I buy...
* I'm looking to have one resleeved by a vendor soon.
Thanks for the help

Default casting number

This is one of the numbers that will work: 12571043 This number is cast on the front face of the block.

Hi Steve,

I guess the new MID wet sleeved block that you are doing for me is a #12571043?

You might want to think about posting some pictures of my block being machined etc, for some of the posters on this forum.

Cheers,

Mark.

Default Mid

Correct Mark. You got one of the three new blocks I have in stock. Another is for a shop customer in Texas the last is going into a Time Attack Corvette for a local shop I am sponsoring.

Have four more coming in to replenish my stock.

I will post some photos of your block next week.

Steve

No worries, just saw his question mark and figured he was looking for an answer, when in fact he is dealing with the right guy anyway so all good.
