Tony, sorry it was not my intention to confuse you. I only wanted to share my experience with you. I bought a complete system of 48IDAs from Inglese last year and I'm more than happy with it. For me it was important to have a system available that can be easily installed because I wasn't so familiar with Webers at that time. In addtion to that it was also never my intention to completely overhaul the engine. What can be used should be used.

But now after having gone through this process I would buy the single components (carbs, linkage, fuel line, manifold) instead of a complete system. This way, I think, a lot of $$$ can be saved.

The factory setup/jetting of the Webers is a street setup and not that different from Inglese's setup. Jets and tubes can be easily purchased and changed based on your's and your Cobra's preferences - you even have to change the jets of a "ready-to-bolt-on" (complete) system because each Weber system (in combination with the engine, ignition, air filters .....) is a unique one.

So be aware of the fact that you even will have to fine tune a complete "ready- to-bolt-on" system.

The following cam was advised by Inglese (Dan Miller):

Intake 0.298 at cam .477 at valve
Exhaust 0.298 at cam 0.477 at valve

Intake 290 degree advertised 222 degree at .050 cam lift
Exhaust 290 degree advertised 222 degree at .050 cam lift

However, I decided to use the my "old" cam:

Advertised duration: 288 intake/288 exhaust
Duration @ .050 in. cam lift: 226 intake/226 exhaust
Gross valve lift: .512 intake/.512 exhaust
Lobe separation: 109 degrees intake/119 degrees exhaust
Peak horsepower rpm: 6,000
Peak torque rpm: 2,800
Fair idle

It's a Ford Motorsport roller tappets camshaft (M6250F303).

I hope this is some helpful advice .... and one thing is for sure:

"Webers forever !!!" ..... the look, the sound, the smell ......

Best regards,

Walter


Matt, thanks for your ideas on how to install such a stop mechanism. I'll try it out.

Best regards,

Walter
