So um what grade of fuel do you all run, regular, premium. regular with lead addititve, stuff like that? Tks in advance
I run regular straight from the pump. Problem with this question is there are so many diffrent levels of engine modification on this board. Assumeing your '73 302 is stock, you should be fine on regular.
Regular gas should shoot you fine. It's what I run But with my Comet when I get her goin w/ the new motor I'll run mid grade if it needs it (ping)
