i have a book that dynos several popular 5.0L mods, and throttle bodies are the biggest pretender out there. On a 400 hp beast, a 65mm throttle body only gained like 3 hp over stock, a 70 was about the same as stock, and a 75mm actually made less power. I wouldnt waste my time on throttle bodies.
TB got my car slower
