For some time I have wished to start another thread dedicated to a single variant - the Countachs built @ Sant Agata with the 6 Weber (44 DCNF) vertical twin-barrel carburettors, the 'Carburatori' version of the now-legendary 'Motore Tipo L 507 V4', affectionately known these days to enthusiasts the world over simply as the 'Countach Downdraft'. Those who love the Countach Downdraft possibly do so because they view it as Ingegnere Guilio Alfieri's stroke-of-genius return to the original Lamborghini V12 Downdraft concept - think Miura. Or simply because it is the most powerful production variant of the Countach ever built by the Lamborghini factory. The intent of this thread is to provide a resource for the QV DD, to the benefit of the car-community at large with useful information. I will do what I can in my spare time, and I invite all to participate with historical & technical information. We are all here to learn! This thread has nothing to do with market values, is not being created to boost values, or sell cars. Its simply an enthusiast's resource, nothing more, nothing less. Besides, there are dedicated auction & values threads elsewhere. I especially thought it essential for me to start a thread on these cars, because recently I have come upon some material that has never been published or shared anywhere, courtesy of some of the men behind the machine in Italy, all of whom have generously supported the effort to uncover the exclusive material. I humbly propose this thread as a small resource for the Countach Downdraft. Please enjoy.
