I think I know what you are thinking about, having side draught webers on my car, though with an airbox. My installation is a little different from yours, being based on a copy of the original S-manifold, which has the carbs sitting in a 15 degree tilted position. The inlet is thus well above the fuel tank. Here's a photo of my installation: The usual solution with the straight manifold like you have is to reduce the size of the fuel tank, usually by cutting it off an glueing/plastic welding it together. That will allow an airbox to be fitted. The alternative is to fit a single downdraught carb on the standard manifold. The Holbay Fast Road cam deals very well with this induction system on the Solex 34CIC carb from the standard 2.2. I used to have this setup, including the 4-in-1 exhaust manifol until I converted to sidedraughts on mine, and the standard cam still allows plenty of breathing to the cam and the engine spins happily past 6500 rpm. So you will not miss much power with that installation, but the sound will be much different - lower, that is. This is a bolt-on conversion. Fuel supply may have to be changed a bit, though, depending on how it is installed now. This is my engine room before with the single carb: /Anders

No problem, Tog. The manifold was offered by Simon, he still advertises it, but I don't know if he has any. It's a replica of the original S-manifold. http://www.simon-auto.de/My airbox was welded up made by a friend out of mild iron plate. I have the drawings if you want to copy. Yes, I'm still using the 4-in-1 exhaust with the Weber's. Your car is Zac's old car, right? If so, ask Roy Gillard - he would know for certain what cam you have. I think it has been well prepared. The 2.2S is not noisy since it also has an airbox on the inlet. Here is a photo of the installation: http://gallery.dinsen.net/v/biler/Matra/technical/carb/other/DSC_0386.JPG.html/Anders

No, it's not that car Anders. Jean-Luc Girard has bought that Murena. This one was George Bell's car. I suspect it has a Holbay cam, particularly if it was done by SCU in the eighties, but many of those cars were not set up well in my experience and opinion and the 45 carbs. are too big, drink fuel and the power and delivery is not as good as yours was when you got it from me.
