[QUOTE="mightymouse, post: 3076686, member: 15253"] Holley carbs were popular because they were so easy to tune. Get a 3310-1 (my favorite for the street) and a Holley "Trick Kit", and in a matter of minutes you could change jets, power valves, pump shooter sizes, pump cams, and vacuum secondary springs. No dyno tuning in those days, but if you knew what you were doing you could balance jet size, power valve number, pump cam profile and pump shooter nozzle diameter, and vacuum secondary opening profile to get the performance characteristics you wanted. The changes could be quickly and easily done, and that's why Holley carbs out-numbered anything else on the street and/or the strip by a wide margin back in the day. Q-Jets and AFBs could be tuned as well, but not as easily or quickly as the Holley, and not with a parts kit that could be bought off the shelf at the local speed shop. [/QUOTE]
