Race & Performance - TPS provision, 4 Corner Idle, No Choke

Absolutly feature packed!

The New Edelbrock VRS-4150 Race & Performance Carburetor ED1308 is a 750 CFM & street friendly but race ready. Has more features than the Holley Carburetor, Holley HP, APD Carbs and Quickfuel. The 3.75“-tall cast aluminum main body fits all 4150 and 4500 carb flange manifolds without requiring an adapter plate. The 850 cfm Edelbrock included a street throttle arm, Moly-coated throttle shafts and built-in provisions for a standard GM three-wire TPS mount. Edelbrock have add features to the ED1308 850cfm carburetor that are ideal for any user. Multiple vacuum hook-ups keep this Edelbrock carburetor usable on the street but still ready for the track with larger capacity fuel bowls and four circuit billet metering blocks & screw-in emulsion bleeds. All of these Edelbrock features make for easy tuning and great versatility in many applications. The 20% larger capacity fuel bowls feature internal ribs to control fuel slosh, and a sculpted baffle directs incoming fuel to the sides to minimize bubbles.

The floats have corner cuts to avoid shutting off the fuel flow during hard cornering, and jet extender notches and jet extenders in the rear to keep the jets covered in fuel under hard acceleration. Edelbrock VRS carburetors allow users to externally adjust idle bypass air and the adjustment screws are accessible without removing the air cleaner/scoop, unlike the the Holley carburetor, APD & Quickfuel. The advanced idle circuit features interchangeable idle discharge jets in all four corners to allow for a smooth, clean idle with the use of big, low-vacuum camshafts. Normally found only in high end racing carbs, the Edelbrock 1307 VRS includes fully adjustable intermediate fuel circuits, which help to provide incredible throttle response. Finally, for greater control at high RPM, the high speed/main fuel circuit is split into two bleed circuits – one each for the lower and upper sections. As an additional feature, the power valves are located on both primaries and secondaries to support optimized jetting. The power valve will add fuel as necessary while the power valve protection circuit prevents diaphragm damage from backfires. Absolutly feature packed!

Notes:
