LS7 question Have a 07 Z06 that has the LS7 in it. I made 863 RWHP with this motor and now I need to rebuild it. My question is if I put good rods and good piston and use the stock crank will this help the motor strength wise also what can I do about the sleeves? Thanks for any advice!!
It would be advisable to resleeve the motor as factory sleeves are the thinnest of all factory blocks. RED or ERL plus other companies can do this.
I would just sell the shortblock and have either above mentioned company do a resleeved alum 5.3 or just go straight to a Dart LSNext block for no headaches.
If you run different rods then the crank needs mallory to balance properly ($300+ extra on top of machining/balancing). So plan on a new dry sump crank from pretty much any company.... and some quality forged rods/pistons.
If I were going to this extent and you already have 6 bolts heads... I would not do a 4 bolt style block.
