OK guys. I'm getting ready to buy a bbk throttle body/egr plate for my 5.0. I'm just curious as to which size would be best. Here's my mods so far: cold air intake, underdrive pulleys, headers, x pipe, flowmasters, 3.55s. This winter I plan to cam it and do an injector and pump upgrade. I'm guessing the 70mm would work, but u guys know best. Thanks!

 

65 would be fine 70mm overkill on stock intake. no need for bigger injectors on a cam swap with stock heads/intake. you aren't going to net any gains from the TB anyways other than some slight upper rpm throttle responce, I'd go woth a 65.
