Author Topic:   What kind of carburetor?
posted February 16, 2004 09:26 PM
I was wondering what alcohol carburetor is the best for a wissota modified? Also wondering what size jets people are running with a 347 Ford with N heads? New to a mod and any information is appreciated.

Thanks for the shameless plug, Graham! :-)
We're here to help in whatever way we can.

The 347 motor with N heads is a nice combo. The jetting to use depends completely upon what carb is being used, and how it's built, not to mention air quality (temp, humidity, etc).

As for who builds "the best", there's many many "best" builders out there. And one's success or satisfaction with a carb's performance really doesn't have a lot to do with WHO built the carb, it's really in how the carb is set up for the application and how well the user is able to tune it on that motor.

That motor would probably work best with a 750 HP bodied alky carb, but with the 850 base (1 3/4").
On slick tracks, depending on the surface, etc, some guys prefer a vacuum secondary that's tunable by the driver (remote cable) and with a standard 750 baseplate instead.

Whatever "flavor" of carb you go with, be sure and choose a builder who'll work with you in tuning and after-sale support so that you're continually satisfied by performance throughout the season.

Hope that helps,

I would like to thank everybody for their responses but I'm still not sure what to buy. Most of the people I've talked to have said either a C&S or a Willys but it never hurts to get other peoples opinions. I totally agree service after the sale is one of the most important apsects and I've learned that through the years with anything you buy.

the Holley HP's will perform just as well as the "big name" companies and for about half the price.

Here is my opinion. For the most part an off the shelf HolleyHP or Demon would perform well for most people. But if you want the little extra then go for a custom built carb sized and built for your application. The trouble is if you build it for 1 specific application it may not be ideal for another so you still have to compromise to get a carb that performs well on several combos unless you want several different carbs. And as far as custom carbs go there is prob not 5HP difference in them if the builder is reputable. I would prob lean more to a builder that works more with dirt track racers and I would look for how easy they are to work with and how responsive and willing they are to help. For everyone that says they love one carb i have heard another that hates it, so you have to take everything with a grain of salt.
