Holley 1945 Rebuild

So a larger jet doesn't necessarily translate to more power? I'm sorry, I'm used to throttle bodies. The only reason why I ask is because this is for my brother's 76 valiant and I'm not sure how it ran with the stock jet. Should I go ahead and swap it to a 62 jet regardless? My brother has little knowledge of mechanics and will rather send the carb back to me in the mail before attempting to swap the jet back to sock.

Thanks for being helpful, I really appreciate it!
