Stop in for a cup of coffee

kinda wondering how a 10.5:1 318 would hold up to big rpm with a stock crank since the stroke is so short...
Why? It’s the same block as the 340 that was known for its quick reving, high reving performance. Only difference is the bore/pistons and the heads. They shared the same crank. And all LA 318s used forged cranks throughout their life
