Forged pistons and rods are overkill. You'd be hard pressed to rip up a stock bottom end with the kind of power you'll likely make. To run it hard, which it sounds like you plan to do, and to be reliable, you need oil squirters to cool the pistons, which means you need a td block, or to tap your existing block and install oil squirters. To use oil squirters, you need pistons clearenced (td stock or na modded.) The purpose of using an improved bottom end on a gasser is to lower compression. TD and D have the same compression, and same bottom end sans squirters, there's just more heat, which is addressed by the oil hitting the piston bottoms, carrying it away. Some have run na block turbo'd with some success, but to really flog it, spend the money, do it right, and go true TD. Your simplest solution is to go source a worn td, rebuild it stock with oversized pistons, and intercool it if you want more power. You'll have the same or less money in it, and it will be reliable.
