Throttle Body Size
HI!... I took a DBW 75MM TB off a newer 5.4 3 VALVE and bored it out to 82mm. I converted it over a cable drive instead of DBW. I then had a buddy at a machine shop make me up several prototype butterflys. He said it was a pain in the @$$ to make them. They fit perfect, and it was a nice piece, until it accidentilly got dropped off a workbench and cracked into many pieces.

that sux! i was thinking of using a throttle body spacer as a template tig welding a 3" piece of aluminum pipe to it fabricating the flap and bar and linkage.. but thats to much work for the tools ive got..
Ok, so I'm resurrecting a 12 year old thread....whoopity-doo....it's the most relevant thread to the question I have without starting a whole new thread for something that may have another thread for it.
I have a 98 F150 with a 5.4. I found a barely used aftermarket 75mm throttle body in the garage, and I keep thinking that I remember trying it out years ago when I first got it, but I think my truck didn't run quite right. Does a bigger throttle body like this require a tune for the truck to run right? Would it be worth the time & money to get a bigger MAF sensor? How big is the stock MAF sensor and what sizes are available for aftermarket MAF sensors for the 5.4?
TIA!
