Is bigger always better?

Ok I got an LS and am, Hopefully, getting a edelbrock Victor x intake manifold. Now on the website it states that they recomend a 65mm throttle body, now my question is a bigger throttle body better? I wasnt sure if there was a point where there isnt any more air going in but just rather a bigger price for something bigger and useless. Thanks

I don't profess to be a know it all in engine stuff, but no, bigger isn't always better. you want the most airflow going in your engine possible, a too big tb will probably lower the air velocity, which might reduce overall flow.. I'm sure it's more complicated than that though.

too big and you will lose flow and torque. stay with the one that is recomended
