na ls7 build... is sleeving needed
So I have a standard bore ls7 that I just picked up. Its got some mystery flat top pistons, lunati pro billet rods, and a lunati crank. My question is is it necessary to re sleeve the block? I plan on maybe running g a 200-250 shot. This is a street driven six speed car.
Thanks for any input

Not saying for sure that you can't do it without sleeving but I have quite a few LS7 cores here with cracked cylinders due to higher cylinder pressure and OEM cast iron sleeves.
Those sleeves were not designed for a 200 to 250 shot of nitrous. I know people will think I'm biased because we sleeve but I thought I would respond to this because I see way to many cracked blocks because of this.
Good luck with your build!

Building an LS7 based engine is not cheap - why cut corners now. If you can afford new dry sleeves, it would provide a lot of insurance for the future. Last thing you want is to have to build this engine twice.

So I bought a disassembled ls7 shortblock below are the pictures of the pistons. I am having a hard time getting info on brand and specs. The numbers on the skirt are
809ts & 28583
Thanks, Nick
