The LS7 utilizes a 4.125" bore. The LS7's titanium rod is a weird length, and will require a custom piston if you choose to go aftermarket. No, you won't get a 6 liter block to go out to 4.125", so those heads are pretty much a no go, unless you find a big bore block. A good used LS7 block is much like a unicorn.
