I have just got my motor pulled out of my 01 trans am, I was wanting to know what i can do as far as piston sleeves? i want to use my stock crank but i want to get the biggest pistons i can? so can i put new sleeves in it? if so were can i get these, I blew my car up and am just looking for the cheapest way to get a little more power, also i will be getting my heads rebuilt and ported milled down, a new cam and 3.73 gears. new clutch. i have read that you cant bore of hone a ls1 enought to really make a diffrence. so help guys and some address of a place were i can get larger sleeves if that will work ??????? thanks

 

If you are looking for the cheapest route sleeves are definitely not the right alternative. You are right to say you can't bore an LS1 much because the max for your 01 is 3.910. Just buy a forged 402 or 408 shortblock from one of our sponsors and call it a day. You will spend more on getting sleeves installed as well as the crank and pistons to go along with it than you would the 408. Another option is a 418 L92 setup.

 

You can also get a 383 rotating assembly for just over 2K and use your stock block.
