Torque VS. Horsepower

And for all the peeps reading this who are assuming that a bigger throttle body will give there car more power because it allows more air flow you have to first look at the cubic inches of your engine (or take forced induction into account). You have to find out volumetric efficiency at your max rpm for your engine size with what ever TB your using. For instance on the 350 example in the article.. 350 cube motors can rev to 7000rpm equaling a 465hp potential at 730cfm air flow through the Throttlebody. Does mean your going to get 465hp.. It means it will ALLOW 465hp.
Same with exhaust.. It doesnt give horsepower. It ALLOWS it.

Throttle bodies also, FWIW, should be sized accordingly to the intake manifold volume, vs the runner length.

All I have to say is," knowledge is power!".
Also, it is great to read some of these responses. As I usally sit here and read most posts I visualize some young kid who is paying others to work on his car and then is trying to bench race with those of us who do our own work. I am not one to sterotype people, but it is what I think of as I read some of the posted responses. Sure, sure you have to start somewhere, nobody was born with a wrench in their hand. Yet, it is refreshing to hear intelligent responses from those of you who know a thing or two.
Thanks,
Mark
P.S. Torque rules!
