I was thinking of getting the bbk 75mm throttle body for my 99 5.4. I was wondering if i would have any problems hooking it up or have to drill any holes bigger.

 

u wont feel an difference gettin a larger throttle body... yeh i made see like 3-5 hp on the dyno but nothin u will feel save ur 200 bucks and spend it on some electric fans its better bang for buck. u can port ur stock TB from 65MM to 70MM theres a guy Ted on here that has a good instructional on it. i ported mine along with my intake elbow. and saw a gain.
