Weber carbs have always interested me but I've had any experience with them. Has anyone here used them on a smallblock and if so how many, which manifold and which carbs, IDF or DCOE style? How big were carbs, and most important is did you like them or were they trouble, how did they perform??
 
I have used several Weber carb setups on Small Block Fords, in Pantera's They were the 48 IDA's
They are difficult to setup, but once you get them tuned in they run well. Best results is you should run a cam that is for a fuel injected engine, since each cylinder has a venture. One engine was a custom build with around 500 hp. at that time. The issue with the Weber's is the runner length, it is more suited to lower rpm, short intake runners.
My experience is to stay away form Ingelese, he was hard to deal with and expensive.

In this day and age, if you want to "buy that much trouble" why don't you just go with EFI?

IDA repops are only $130 on eBay now from China. Supposed to use weber parts. Getting them to run together is a challenge. And the intake will be $$$. EFI it with stacks.

Don't know what year,A friend has the small V6 in his Chevy Blazer.My buddy messed with several Holley carbs and never was satisfied. Swapped to the Weber and never looked back.And it wasn't a Weber AFB/Carter/Edelbrock look alike.Not sure of the model but it may be a 2bbl with a adapter. The engine has a aluminum 4 bbl intake.

You mess With Panteras? you need to come buy my M code Cleveland. I'm never gonna get to it.
 
If anyone knows of a smallblock manifold I sure would be interested. I'm even considering putting a new top on my blower manifold to see if I could get it to work
 
Or........SB.........In fact I own one of these. Bear in mind I am NOT talking about old school mechanical.........I'm talking about converting these to EFI with such as Megasquirt, or Holley HP etc etc

There are two big issues with stack injectors and really any IR type induction system.

The first is the fact that reversion exists in any induction type, and without a plenum the reversion issue is magnified. You can change the cam timing to help it a bit, but you may lose power doing it.

The second is the limit of airflow due to the stacks. They are terribly flow limited. The bigger the displacement and/or RPM, the sooner it shows up.

I learned in 1986 that stack injectors were killing a 377 inch SBC I was tuning. Over 6k it was out of air, and I couldn’t pull enough fuel out to get the fuel curve where it should have been. The tunnel ram made way more power.

Even EFI won’t fix any of that, as long as you are injecting the fuel at the valve cover rail. Even timing the fuel still has issues.

I’m not a fan of any stack injection system, or IR tunnel ram deal.
 
Something tells me that stack flow on a mild SB or slant is not going to be the limiting factor. The same problem however, would exist on a weber!!!!

There are some impressive engines use IR systems, some of them "pretty big"

Yeah, as long as it’s a mild build it’s not nearly the PITA it is when it’s for an all out performance deal.

I actually had more issues with an IR TR deal I tried in 1987 before I went to MFI.

That was MISERABLE. The carbs were pissed off all the time except over about 7k.

Who knows...I’ve learned more about carbs so maybe I could make an IR deal work, but I doubt it because if it worked, more guys would do it.

I’m old enough to know just because I can don’t mean I should!!!

oh, i agree EFI looks good when dressed up as something else :lol: and i am just talking about looks :thumbsup:

there's always the low buck approach

I've been working with engines powered by carburetors for 35 years. the webers: IDA, IDF, DCOE, DCNF, ... are very good carburettors. Sometimes it works very well and sometimes it takes time to successfully adjust the engine. May at the end the result is very satisfactory
