Yes there is a guy on here as tkoforpresident. He is doing the swap and using the stock bottom end. Im been watching his build to get a better idea of how I want to go with mine. But im not keeping the bottom end stock for sure. You can read about his build in 3x00 section he has alot of info on the different types of things going on in there. Very smart guy.

The ONLY way to get away with stock pistons is by using the lx9 3500 heads.

If you go with the heads off a 3100 or 3400 then you will need to swap to pistons that match those heads.
