I believe that piston will not work on a ls1 block as the recommended bore size on a ls1 is 3.905. And that piston is set up for a 4.00" crank, are you using a 4.00" crank?

These pistons are designed for a 403cid motor.

Yes that is the size you need. 3.905 is just a .005" hone on a stock ls1. But you also need to make sure it is for the correct stroke. which it is for a stock crack. It has something to do with the location of the wrist pin.

im gonna be using the stock crank, ive heard of them being good to 1000hp, but these pistons and 6.125 eagle h-beam connecting rods! 1200 bucks isnt bad at all for that!

Are you taking it to a machine shop to have to work done? The whole thing is going to need balanced and clearances checked.
