Webbers

[Hottrodder427]

I want to go with a Webber carb set up, pros? Cons? How original is it?

[GoDadGo]

The 427's came with either a single Holley Carb that had center hung fuel bowls. The 427's that came with duel Holley's had side hung fuel bowls and were mounted backwards. You can go to RM Auction, Barrett Jackson, Auctions America, Goodies among others to view original CSX 1960's Vintage cars if you want take a quick peak. Look up the Dick Smith #198 Cobra because the MK-4 most closely resembles that famous car. Webbers were typically on the 289 race cars which in include the Daytona.

I'm Not Sure About The CFM's of the Holley's that were used. Would have to research that a bit.

A friend has an ERA with webbers. I have to admit there is nothing quite like them. It's about as exotic as you can get. I know there are probably people with those setups who have had excellent results. You may want them bad enough to take that chance. Make sure there is an expert who can work his magic on them. Personally, if I had a FE like you are building, I would go with the fore and aft Holleys. Two 600s would work great and they look almost like they are one long carb (so close). It's a bad a** setup. BTW: my friend had to spend a substantial amount to get his right but once done, they run beautifully.

Good luck with your decision,

WEK.

Gotta love exotic carb set-ups. I'm a fan of Webers, but they do work better at high RPMs and are therefore better suited to racing. For street use, they can be tuned to work and once set they should be relatively reliable, but you'll probably get better driveability and reliability out of a single or multiple Holley (or similar) carb sytem.

Here's a pic of a tri-power set-up I had on a 289 in a '65 Mustang - this uses three modified Ford Autolite two-barrels on a custom manifold. The progressive linkage was a pain to get set just right, but it did work well once de-bugged.

Kind of depends on what you want to do with the car. Like the others have said, for originality some of the 289 cars had Webers. I don't think any of the 427's did.

Jim Inglese (not Inglese Induction Systems) is the go-to guy to set them up if you decide to go that route. He really knows his stuff.
Webers look fantastic, are really kind of fun to learn how to tune. Use good fuel filters. They will get gummed up if you have crap in your fuel.

Did I mention they look fantastic? :)

For the record (not to mention originality ;)) it's Weber, with one "B".

Seek out some of Erik Treves' posts on his Black Mamba FIA car which is running Webers. He had a sorting out curve but has it running well now.

A year or so back, I accidentally stumbled into a shop that specializes in maintaining and tuning vintage race cars. The shop manager kindly showed me all the cars in the shop. One was a Lotus 23, equipped with Webers. I mentioned that I had heard how difficult they are to tune. He said they were really quite easy to keep in tune and proceeded to remove the cover from one and point out the details. That said, this shop offers concierge service for vintage racers, even to the point of accompanying the car owner to the track and taking care of the tune over a race weekend. The guy said he would tweak the carb several times during the day to adjust for changes in temperature and humidity. Bottom line is that Webers work fine if you REALLY know what you're doing. But it doesn't sound like they can be set once and work from then on. So, if you know a mechanic like this guy, get to be good friends with him. Otherwise, I'd not recommend Webers.

Webers are just carburetors. But there are several areas that need special attention. Cam, fuel pressure, air filters, and float levels are some of them.

The initial setup is critical, and this is not my first dance with webers.

These 48 IDFs were installed in 2008, and have not been adjusted since. I have been to sea level and to 10,000+ feet of altitude without problems.

I have 48 IDA Webers on my 289 build. I also had them on my GT40. Both engines are 331. Webers can be tricky but once you've done them it's easy to maintain. On both my builds I had to change the as provided idle jets and idle jet holders to smaller numbers. Cam selection Is critical and you need a special regulator to keep pressure to 2PSI.

No weBers for me, dual quad I guess

Here is an original CSX coil spring with Webers at SAAC40 last year. Pete Brock (yep, that's him in the background) sat next to it and admired it for hours.

I gotta say, for those of you who put these on your FFRs, they look awesome!

I'm still thinking about what I'll use for my current '65 Mustang race car project - Pro-systems 4 bbl, Stack EFI, or Webers.... hmmmmmmmmm.

[NukeMMC]

Something to consider is the Weber IDF instead of the more frequently seen IDA. The IDF, as unmodified, has a 3rd progression hole, allowing for a more linear power band thru the rpm range. It also has a cold start circuit the IDA doesn't have. These things, in addition to the smaller size, make them more "streetable" that the IDAs.

They do look pretty good also. Here's a set on a SBF FFR 33 at a local show:

Wow! Those look awesome.
