Throttle body question
sorry if this is a duplication, but I couldn't find the thread I read before about the different types of throttle bodies. I have a 2001 F350, V10 of course. I bought the Poweraid throttle body spacer that has 2 holes in it (for the twin bore throttle body). However looking at my TB, it appears to be a single bore type, with one single oval shaped butterfly. Is there in fact 2 different types of throttle bodies??? Seeing how the spacer I got looks to be made for a twin bore type, I can't see it helping at all on a single bore type. Anyone???

Stock is twin 57 mm.If it's a single it must have been changed, probaly an AccuFab tb.Now as far as the spacer is concerned if you remove it you will see an improvement,some disagree, but I think they are snake oil.I have a BBK twin 65mm and it works great with a noticable improvement.If you do have the Accufab, the spacer is hendering the bigger tb because the spacer is designed to work with the stock tb.
It's an 01 F350.

V10KL....how did you make the throttle cable fit with the BBK TB? I installed one (1711), and the damn cable had too much slack. Couldn't figure out how to correct the problem so ended up pulling the TB off and returning it.
