Race Class Carburetor or Street Carburetor?

 

Although electronic fuel injection has dominated the street and racing scene for three decades the old reliable four-throat atomizer remains as popular as ever with hard core performance buffs. The beauty of carburetion is its wonderful simplicity – the mixing of air and fuel along with the modulating of throttle plates and accelerator pumps. No wading through a sea of confusing electronics. What’s more, few things are quite like the thrill of goosing the throttle and hearing an engine respond. Try that with your late model, fuel-injected, drive by wire ride.

These folks take serviceability even further with extraordinary attention to detail – lightweight billet aluminum construction, CNC machining technology, swappable idle air bleeds, easy to service metering blocks performance-tuned for street use, and four-corner idle adjustment on mechanical secondary carburetors to help fine tune the idle when you have an aggressive camshaft profile. Swappable idle feed restrictions further expand the idle adjustment capabilities.

Size Matters, Bigger Is Not Always Better!

“This year, Proform added a new line of Race and Street Series carburetors that feature a rich Black Diamond finish on the fuel bowls and main carburetor body. In addition to looking awesome with the purple billet components such as the metering block, the finish has some fuel temperature reducing properties that make it more than just a finish. Cooler fuel is a good thing. It helps your engine make more power,” Platt tells us.

The Proform carburetor package is complete with high quality light weight die-cast aluminum fuel bowls with fuel level windows for quick visual reference. Float level changes do not require removal of a sight plug with the risk of spilling fuel. Proform’s bowls come equipped with 3/8-inch inverted flare fuel inlet fittings and will accept all conventional dual feed fuel lines compatible with Holley four barrel carburetors. No hunting all over the Web for just the right fittings and dual feeds. Another great premium with the Proform is parts availability. If you cannot source Proform parts, parts for these modular carburetors are universal. Power valves, jets, boosters, metering blocks, and other items are interchangeable across brand names. You’re never out in the cold if a problem arises.

Choosing the right carburetor boils down to what you see when you take these guys out of the box. Proform takes the business of fuel distribution seriously and pays strict attention to quality.
