This BBK 85mm F-150 throttle body will deliver more horsepower and works with both OEM air intakes and aftermarket cold air intakes

Question: How can an 85mm TB be compatible with factory and aftermarket intake components designed for the factory 60mm TB?

Maybe because the factory TB is 80mm!!

I did say I believe that it is 60mm, I did a quick search and cannot confirm the exact size, I'm seeing 73mm and 80mm for stock 6.2L.
Maybe someone else can find the specs.

The BBK upgrade is 85mm, so I was completely wrong, sorry.

You guys had my little brain all screwed up when I started reading this thread! I didn't know I had wandered into the forbidden zone.

Lol, I only read the Off-Road supplement.
The whole manual packet is still untouched.

So 80mm it is, thanks!!!

I have a 90mm GT350 TB that I want to try on the Raptor, need an adapter plate and more research.

The problem I have seen with upgrading the TB on a stock NA 6.2L is Ford already maxed out the TB size with the 80mm, the engine can only pump so much air.
Putting a larger one on does nothing without internally upgrading the engine with a bigger cam or increasing the C.I.D. or supercharging.

You're quire right, sir. The danger with increased volumetric capacity in both the intake and exhaust tracts is that the intake and exhaust airflows can stall at low throttle openings and when the throttle is closed abruptly. That stalled air is as bad for engine performance as stalled air is over an airplane's wing. If throttle response is the goal, then stalled air is your enemy.

unless its been ported it should be 87mm. as far as adapter blowfish racing adapter will allow a stock gt350 tb to mount to a 6.2 intake manifold, atleast on my 250. i was going to use one of these in conjunction with other mods. the tb and adapter are sitting on my garage shelf. i have also read that tuning for this throttle body can be a pain on the 5.0 depending on the year.
