what's the point of forged internals in a

I've always wondered the same thing about kits for us 4.6L guys. The stock crank and block in our engines will take well over 600hp. It's the rods and the pistons that'll take a crap long before that.

They do offer rod and piston kits alone, but since the Modular Engines are internally balanced, you're kind of responsible for having it rebalanced on your own. When they sell the engine kit as a crank, rod and piston combination, I believe its pre balanced. Perhaps that's what's being done with the stroker kits for the OHV engines as well. I would imagine that when bought in bulk, Forged Steel cranks aren’t that much more expensive than the stock Nodular Iron ones….and it is always a nice selling feature. That’s probably why you see them included in most stroker kits....since they require a rebalance as well.
