440 Intake for Full Race?? - Our Lil Red Express

Something to mull over... A larger port, that is lazy (meaning you're not turning the rpm to make full use of it) will be harder to tune and affected by weather. The Sr's area very good head and in std port opening can make some great horsepower and more important, a solid flat torque curve. I think, if it were me, and the combo lost .5 second, but the engine leaked down ok and inspected ok, I'd be looking at more thna the engine. What was done to the transmission? When was that last looked at? The rear end?
