Right jets for the 302 cui 4V

Hi,

i´m new here, my name is Tom i´m 27 years old and i am from Austria.
I´m driving a 68 Mustang convertible 302cui 4V with the Autolite 4100 1.12

Which jets do you guys recommend for this engine?

At this time i´m still driving with one 54F on primary side (the other one is unreadable)! On the secundary side is one 62F and one 54F (i dont know why there are two different jets on ONE side!!!

Which jets should i use for economy drive with enough power???

And where can i buy them???

Thank you for your help

Best regards
Tom
