Cam match to intake

You said it doesn't feel like a big block when you stomp it. Is it tuned right and is your gearing and chassis dialed in? You have to figure that the late model cars we drive everyday approach or exceed the hp that 440 is putting out so it may just take a little more engine to impress you.
Life's a ***** when an old iron block 440 doesn't impress as much as the new aluminum plants do. God I am not looking forward to driverless battery cars!
