650CR AED 650HP Crate Engine Oval Track Carburetor, Gas

With the advent of many new crate engines used for racing, most popular are the GM 602 and 604, we have developed 2 new carburetors. One is a 650HP and the other is a 750HP. Many tracks require one of the 2 carbs in stock sizing and appearance. We spent many hours on the engine and chassis dyno working out this combination. We start with new castings & fulling machine the bodies for gasket sealing. These are totally blueprinted for sizing on all throttle bores. Boosters are blueprinted for maximum signal strength, centered, & fixture installed. All fuel circuits including accelerator pump & metering blocs are sized and calibrated for maximum acceleration and power. WE also make all circuits adjustable for easy tuning. We use special custom machined weighted floats for corner loading fuel control. After final assembly all carburetors are Wetflowed and fuel curve set. We leave nothing to chance providing rigid Quality Control procedures throughout the machining and assembly process. All AED Carburetors are test run before shipping. We recommend the 650HP for the 602 crate engine in all applications. For the 604 engine we recommend the 750HP version for larger tracks or when the rpm band is fairly narrow. With a short track with the rpm range varies more than 2400 from minimum to maximum the 650HP is a better choice. These are custom built so we can make changes depending on specific rule requirements.
