Carburetors off the shelf vs built....`

If it were me I would have a carburetor built for your application by a good carburetor builder who knows his stuff. A properly built carburetor will have many of the same features as a stock Holley or Demon but it will work at a level that's a notch or two higher than an off the shelf piece. Carburetors are mass produced items and so it seems that it's about impossible to build them to as tight of tolerance that's really needed when you want it right or even close to right. Areas like the emmulsion package, booster configuration, idle and transision circuits can all be improved and made to work much better than stock. Special features(950HP with a PCV port for example) can all be done on a built carburetor because it's being built for YOU.

As always, I highly recommend Bobby Oliver at Competition Carburetion as a straight up guy who knows how to do the job right. He builds a top notch piece that works great with no bologna... He's friendly and easy to talk to and he will give you the best advice when it comes to selecting a model that will work best for you. While his work is not cheap buying a carburetor through him doesn't cost much more than a new Holley anyway and he can also work from a core carburetor. In fact in some instances he prefers the older carb bodies you should see a few of the sweet pieces I've sent him over the years.... Give him a call at 775-331-5609..
