Carburetors

  • RWA1222B 1" Tall, HOLLEY 2bbl Spacer -Ported- CAST ALUMINUM Carburetor Spacer. This spacer works best with the 350 Holley 2bbl carb.  If you are running the 500 2bbl carb use RWA1222 open plenum spacer. Includes:
    • Carburetor spacer
    • Gaskets
    • Carb studs, nuts, washers
  • RWA1222C 1/2″ Holley 2BBL carburetor spacer is required when bolting a Holley carburetor onto a stock 2300 2bbl intake manifold (when the EGR plate is removed). This spacer will also work on on any intake manifold that has the 2bbl Holley bolt pattern.  The spacer is designed with a small tapper, this helps with fuel flow and helps create a better plenum under the carb. The spacer is cast aluminum with machined surfaces. Includes:
    • Carburetor spacer
    • Gaskets
    • Carb studs, nuts, washers
  • Out of stock
    We highly recommend this manifold/carb combination for street driving. It will perform well with a stock or modified engine. This is the correct Holley 390 (0-6299) for the small engines . This carb gives excellent gas mileage, as the primary bores of the 390 are actually smaller than the stock Pinto carb bores. When you get up in the rev range the vacuum operated oversize secondary bores open up for plenty of power. The kit comes with a linkage kit to ease installation. There is also a chrome air cleaner assembly that comes with this kit (not shown).
  • RWA 1218 Carb restrictor kit is designed to use in the Holley 350/500 2bbl carburetors. These carburetors are designed for use on V8 engines and will run too rich on initial acceleration on a 4 cylinder engine. Our restrictor kit eliminates the bog by reducing the fuel flow through the metering block. The restrictors are installed under the power valve in the metering block. The kit includes:
    • 2 brass restrictors
    • 1 drill bit
    • Instruction sheet
  • The RWA1215 is designed as a stock replacement for 2BBL street applications as well as being mandated for some oval track racing sanctioning bodies.
