Edelbrock 1407 Performer Carburetors

Bigger is not always better. If you're trying to run a big 750cfm on a small 350 it's not going to work for you'll end up flooding it with gas and you'll kill the performance all around. If you're building  a nice 350 with a good size cam a 650cfm will treat you fine. Good response and great acceleration. A well tuned carburetor, the right size, can be a huge performance gainer!
If you're building a high RPM motor you'll want to use a taller intake manifold, if you're looking for torque you'll want a short intake manifold. Either way you'll still want that same carburetor. Now is when you'll start working with jetting and getting a little more serious. Lean, rich it's all a matter of using the right jets and getting the tuning right.
Edelbrocks "Performer Series" carburetors and intake manifolds can be combined with their great cams and other assorted performance parts. Combining is key! It's all about the combination. Edelbrock has spent all the time and money trying to figure out which combos work well in order to market them. Makes sense that they would only use the best combinations. A good 350 running a nice 650cfm carburetor with a low rise intake and a mild cam can be a great Saturday night cruiser and can push 300-350 horse power if you tune it right. What do you think they would have given back in the day for 300-350 horse power? I know my dad would have paid nicely to just buy and bolt on that kind of performance power. He would have whooped everyone back then.
Dollar for dollar, Edelbrock has some of the best bolt and go speed parts available. From superchargers to intake bolt kits they pretty well have you covered. They've been building great carburetors for decades and they'll continue for years to come I'm sure.
Edelbrock's Performer carburetors feature two-piece, all-aluminum construction for cooler operating temperatures and less warping. There are no gaskets below the fuel bowl level for fewer leaks, and no plastic parts or power valves to blow out. The carbs use easily changed metering rods for precise tuning, and the primary venturi booster is a bottom-feed design for smoother acceleration and better drivability. Also included with every Edelbrock carburetor you will receive a owner's manual. These manuals consist of two sections; Section 1, Theory of Operation and tuning procedures which will help you be prepared to develop your own individualized calibration. Section 2, Tuning procedures will take you through a step-by-step procedure that will enable you to achieve a desirable calibration. For added ease of tuning, a Calibration reference chart for your model of carburetor will be included
