When in doubt... floor it
So I’ve had this big block 1966 440 that my dad’s had forever so I freshen it up a few years ago we dropped at my buddies 66 Polara. I put in some good parts but I never check the bottom end. It had a cast crank X ternal balance balance her on it forever so I assumed it was a cast crank motor. I pull the pan off last night being bored, come to find out it’s a forged crank motor! If I had a cast crank balancer and a cast crank flex plate on this thing and it was internally balanced wouldn’t shake the fillings are your head? Im very confused. It ran very smooth to 7k alot lol
