I love big block chevys. My first experience has been with a 402 bored to a 408. Even with stock heads this thing is a real kick in the pants in my G-body. Here's the deal: I bought a 427 from a friend of mine and I'm not sure what to do with it. I know there's no replacement for displacement but do I really need a 496 in a G-body? The car weighs about 3900 pounds with me in it and it has a 3:42 gear. Even with the "little" 408 it goes from 3 to 6 grand in a hurry in drive. I've debated leaving it a 427 because they can really wind but I'm also a big fan of torque. Having never owned a 496 I worry about the thing totally over powering the tires every time I mat the gas. I don't want to tub the car and a 10 inch tire seems to fit the best in the wheel wells. I'm asking for advise from other big block owners who know what these engines are capable of. Don't get me wrong, I love the "too much is just enough" theory but I like to drive what I build and want a pleasant and powerful experience. My fear is dropping down a gear to pass someone and the rear end breaking loose. Any thoughts?
