Does anyone make a throttle body for the 4.7?? I found a company that had a 70mm but now thier website isnt working anymore. Is this a mod that is worth it??
Dan the fast man does. thefastman.com I am pretty sure...
I bored mine out myself, it takes a lot of time and a lot of checking measurements... I opened mine up to a true 68mm, since thats the size that Dan suggested as best for my application...
yes sir, dan is a great guy to work with and his exchange program is good also, i have a 70 mm throttle body from him, it was 260.00 and when you return your stock one, dan will give you 80.00 back. so it only costs 160.00
upgraded throttle body
