Ken,
I too, don't understand. Any engine that would use stock rods, or press-fit aftermarket rods, would be fine with the stock 400 crank. No 700-plus HP engine would use stock rods or pistons... No engine under 700 HP really NEEDS a forged crank. The stock crankshaft is the strongest piece inside a Pontiac V8. The forgings make high revvers do better... And yes, they're ALL "imported" forgings.
