Just came home from a hard working day. Did some fine tuning on the weber carbs today and installed a new throttle pedal. The car is still in the garage but runs fine. Wondering how it will run on the street (in 2-3 weeks hopefully !!!). I also have installed the fuel pressure regulator and the fuel return line. Pressure is set to 3.0 psi. Runs perfectly. Thanks to all of you who gave advice !!!

347,

There is one thing I gave up during the installation/set up process of my webers. Since each weber installation is really unique you shouldn't compare your engine with the ones of your friends. There is an initial jetting as a starting point from which you move towards your unique setup. It's more or less a trial and error process. I'm not yet at the end .......

For my 347 I have choosen the following initial set up which is a good street setup (as confirmed by CalMetal):

37mm venturis
60 idle jets
1.10 idle jet holders
F5 emulsion tubes (F7 are more common)
150 main jets
210 air corrector
50 pump jets

F303 Ford Racing hydraulic cam with no overlap (288int/288exh)
