Reply to "Weber IDF's and Panteras"

That is the "Inglese" "351c Weber Cam" (CompCams). The CamTechniques is as I recall, .586 lift. That cam I saw run on the track with this setup. In my opinion, the car was way down on power. It didn't even sound right and have that howl you hear from a distance?

But...first off Corey, you have to define the term "BETTER"? Everyone will have a different interpretation of the term. That's where it gets a little sticky (controversial).

The IDAs offer the possibility of this duality, in that they can be "tuned", as in tuned down to make them more livable as a mostly street driven induction system, OR they can be tuned to run them flat out as was done in the 60s and 70s as the ultimate (for the era) naturally aspirated induction system.

The carbs themselves are easily changeable, relatively speaking, from day to day because of the top access to the jetting.

The camshaft of the engine is not.

It is up to the owner to decide the nature of the engine.



To me, it is difficult to live with them on a daily basis with a big overlap cam like those run on the race cars. Being a Walter Mitty type I suppose, that's what I really want though. Dam the practicality?

By the same token, the nature of this setup of constantly wanting more out of them makes running the "Weber Cams" somewhat of a bear trap.

Those cams are simply de-tuned to eliminate the reversion of the fuel.



As with any cam selection, you really have to try both of what you are considering. You can only get a cam recommendation from a cam company. It's up to you to decide which and it is a lot of work to try various cam profiles...but that's the gig?



For the amount of usage I give the car, running the carbs with the open stacks and the big overlap is ok with me. I'm not crazy about all that fuel being blown back, but knowing the alternatives I can accept that fait.

When you select a camshaft, you match it to the flow characteristics of the heads do you not?

If you are making your maximum power at say .650 lift, why would you put in a cam that is .571 or .586?



The simple thing in the end I think is not to get invested into Weber carbs in the first place. The better alternative now is to use the Classic Fuel injection which looks just like them. Then all of this debate on which door to choose, the Lady or the Tiger becomes purely academia.

Problem solved...no more reversion. No fuel in the bowls to be reverse flowed because now there are no fuel bowls?

Everything computer designed, matched, and optimized from the beginning. Then you just tune the setup with your laptop. "Hands on" ultimately is sooo over rated...right?
