So, after reading all this discussion, am I safe to assume that I can bolt on the spare (good) 750 double pumper I have lying around, in place of the tired (and smaller) Holley I now have on my stock 340? Seems odd, since I ran this same carb on my well modified 383 several years back. Am I missing something here, or was my 383 under-carbed???
