I need to know the proper jetting for a dry zex kit on an lt1. I have a used kit and zex sent me jets for 75HP, but I am not convinced that they are correct. They sent me one .082 jet and one .040 jet. I am guessing the larger jet is for fuel, but I am not sure. Please reply if you have any info.

 

you only need one jet. i bought mine used also but i took the computer B.S. out and ran it like a regular system though. the biggest jet zex has is a 125 shot i forget the exact size of it
