The stock bottom end is pretty strong.... But Ti rods aren't the best choice for big power. If you were to do steel forged rods the heavy Mallory inserted into the crank to balance is properly is $300+ alone. So just sell the rotating assembly or shortblock if you plan to make crazy power
The stock block also has the thinnest sleeves of any alum LS block.... How much power are you looking for. What year z06?

If you're only wanting 700hp, cam, exhaust, cai and some nitrous. Or you could supercharge it
