Thread: multiple verses single

What are the pro`s & cons of using a multi carb settup for a street car?What has worked best for you i.e 2/4 3/2 8/1 etc ,i would like a 3/2 or 4 singles, but ive been told its a pain in rump to keep these settups running

You can get more reliable power from the right single 4bbl than from most multiple carb setups, mainly because that's what gets all the development time. Single units are easier to tune and keep running good. But then, if you're running a rod with an open engine, you can't beat the Gee-Whiz factor of a bunch of hungry carbs staring at ya!

A while back I had a '68 427 tri power Vette. It came with 8, yes 8, spare carbs for the tri power set-up.

After much pain and time playing with what I had I wound up buying new carbs and still did not like it. I never could get it properly leaned out. I switched to an 850 holley vacuum secondary carb and the car sprang to life like it had never before!

For what it's worth .................

Good Luck, Kitz

Shoot...

Who`s got time for that when there`s cars to build?that`s what the mailman is for ,to keep the wife busy

I've been in love with 2-4bbls from the git-go when I first saw a set of Carter WCFB's on a Vette, although like R Pope said, the car will probably run better and give less grief with a properly sized single 4-bbl.

I'll add my 2¢ for the same single carb. Much more farting around with synchonization for debatable performance increases at speed. On the street there is no advantage really.

Thanks guys,it seems everyone agrees on a single carb,i like the look of multi carbs ,but i guess ill stay with one. I have an old 2/4 intake but im having trouble finding good wcfb`s for it ,will any thing else bolt up?

The only multiple carb set up that I'd really consider would be 4 Webers. This are set up as straight shot into the cylinder and operate similar to mechanical fuel injection. The only issue is the correct set up of the linkages.

I tried 3 different set ups on my 305. 500 cfm, 3 deuce set up and a 600 cfm. Couldn't get the three deuce set up to work properly, so I put on the 600 cfm and it ran great.

Small AFB's will work on your WCFB manifold, or new Edelbrocks, unless its a real antique that's made for the small pattern WCFB. Then you'll need adapters.

anyone ever hear of running multi-carb sets with only one open carb ( block off the others?). it would give you the ooohhh factor without the maintenance...

just askin... not endorsing it or otherwise... just asking...
