Thread: Single or Dual Carbs?

Tweet

I want to know what you guys prefer, a single or dual carb setup. I have a single 4 barrel Edelbrock carb on my 351 Windsor. Its a 600 CFM carb and the motor puts out 400 HP.
I know a dual carb setup looks great but does it give that much more performance/response/reliability? If I wanted to over-carb my motor I could just put a 1000 CFM unit on and listen to that great big sucking sound!

As multiple carburation goes, I prefer Webers. Nothing like 4 downdraft carbs on a V-8. I look at it as low-tech fuel injection.

As far as preference mine is usually Tri-Power. I've owned a number of Tri-power and Dual Quad cars over the years, and currently have 2 projects that will both be Tri-Power.

My experience on street motors is that correctly dialed in multiple carbs on a properly designed manifold will perform as well and get as good of gas mileage as a properly matched single carb set up. The key of course is to properly match the setup to the engine.

In most cases dialing the combination in is a lot more involved than having to deal with just one carb and of course there's the added cost of a second carb, linkage, air cleaners and all the other little things, but you can't deny the wow factor

You can get as much street power from a single four as any other combo, and it's much more reliable and easier to tune. Leave the multiple setups for the guys who race, and the streeters without hoods (there's no denying the gee-whiz factor!)
