i have a 305 tpi set up that i want to convert to use on my 350 engine. The articles say tha the knock sensor and the esc module need to be changed. Where do i find them to purchase? I am being told by the sellers that they are the same unit and do not require a change. I think they do for my mass air system. Please advise me. Thank you and Have a fun day today!

 

AFAIK the ESC is the same.

The knock sensor however, IS different. It is basically just a little microphone that's "tuned" to the frequency that goes with a given bore diameter.
