No problem, glad I could help!
Is your engine lowered or stock height? How is clearance?
Hey is it my imagination or what, "whatdoyoufeedit" said there was insufficient clearance on the thermostat so he had to rotate the throttle body 180 degrees to make it work. But you didn't turn yours, so what is the deal, did you discover a new way to install it? I'm trying to make my own adapter out of 3/8 aluminum and finding it difficult with just a drill press and a hacksaw.:frusty: I would do it the way you've done it if it's easy enough, fewer chances for a pesky leak.
That is odd I've had the BBK and this mod, they were on two different cars, and both felt a lot better in midrange but really about the same on the strip. Sorry to have to tell you that man. My throttle body is from a F150 also. I wonder if it has anything to do with the ported intake? At least there are still guys doing this mod so you can probably sell the complete deal to someone who doesn't want to have to run all the stuff down themselves. Yea fordguys550 how hard is drilling out the T/B, any trick to it?
His issue sounds like altitude. A tune will help however forced induction is king at his location.
If your measuring hole spacing remember that the center to center distance is exactly the same as the distance from the inside edge, toward the other hole, of the first hole to the outside edge, opposite away from the first hole. I think this only works if the holes are size.
Thanks...I figure I am just going to make this simple on myself and mark the outer edge of the original hole as my center and drill there (drill bit is 3/16" round) and if I come up short, I'll file away the rest.
