Later model Q-Jets you could adjust the rod depth. Earlier models you had to re-jet, spring and the best meter rods for the set-up. But, 90% of the time a base stock 750 cfm Q-jet would run about any thing. If you added aftermarket parts, made it breath better (more air) - the carb would have to be sweeten" it up. Edelrbrock still sells Q-jet main jets, rods and springs. Jets are not that expensive. Summit racing...

Shoot me the numbers off the side of the carb. Lets see what year/application it belongs too.
