I jumped up to the 427 from the 376 opting for more low end torque while keeping the CR 11:1. Obviously, you'll get more torque with more cubes. More airflow = more power. You just have to have the FI to feed it, and in my case it was with twins. There were a lot of guys running stock cubes and hitting close to the same HP. So, after having stock cubes (stock bore & stock stroke), then running a bored and stroked, I think it would be a safer bet to stay stock cubes or maybe slightly bored and stock stroke.
