454 has a larger bore, but i think v6's and the smaller v8's are all the same.

Can anyone tell me the difference between the throttle bodies from the V6 and the V8s? I have an 89 V6 that I wanted to do the "ultimate throttle body" to, but I didnt know if I would get more bang for my buck by finding a throttle body from a V8, possible 454?
The 4.3L throttle bodies are exactly the same as the 5.0 and 5.7 throttle bodies. The only thing that differs between all 3 are the injectors. All 3 are interchangeable but make sure you swap out the injectors.Originally Posted by Hybrid240ZXT
