Can anyone tell me if there is any difference between a throttle body for my 94 Z28 and one for a Caprice with an LT1 motor? I picked up a great deal on a brand new throttle body #17094164. The one for my car is a 17094163. The only visible difference I can see is a vacuum port on the new one. Can I use the new one on my car?
Thanks,
Walter

 

Can anybody help me on this?

 

anybody?

 

Unless the throttle/cruise cables are different, the TBs should be functionally the same

 

I don't believe so. i just bought a 58mm tb off of a car roadmaster.
