Today I went to a you-pick used auto parts/recycling yard and picked up a 3400 throttle body, since I read it has a larger bore. The place was quite big, but I only found one 3400 SFI engine before it began to rain, so me and my friend ripped it out and ran to the building.

It's in so-so shape. Some of it is a little rusted, but nothing that won't clean up.

I'm going to need a new gasket unless I can salvage the one off my stock one (currently on the vehicle). The one on here looked like it was in good shape until I tried to take it off.
It appears that the part the throttle cable wraps around is shaped differently. The flucrum there would slow initial throttle degree changes; would this in any way affect the computer's actions based on the throttle positioning sensor? (It seems to use the throttle as a guide to how much performance I want out of the vehicle, and this may make it try to go fast while the throttle body opening isn't open enough for it to go fast yet.)
