Throttle body

[Booboo]

Anyone have a larger than stock throttle body? I am interested in the dimensions of the front and back openings.

I am getting ready to rebuild the 6.2 in my truck. I am planning on long tube headers, CAI, cams and possibly a new throttle body.

I measured the stock throttle body and the front opening is about 83mm, the back opening is 80mm and the opening on the intake manifold is about 85mm. I assume going over a 85mm would be a waste. Does anyone have the dimensions of the front and back openings of a 85mm throttle body, like a BBK?

Do your research here on those BBK TB.
Don't waste your money on the BBK TB, the stock TB is more than enough.
Plus, no one has ever got them to run right.
I think there are two used ones for sale on the forum.

If you are really going to do the Livernois cams,
then you will need to use Livernois's Tune to make them run correctly as well.
And you can ask them about the BBK or the other brand (I forget the name).

Good luck on your build.

I have the ability to tune it so cams and a different TB are not a problem. Im a little surprised to hear that people are having problems with a BBK TB. I will do a little more looking around to find these threads.

Anyone have experience with these guys? Soler Performance LLC
