One of the unfortunate by-products of the internet is that incorrect information spreads at an enormous pace. I am sure that this misinformation is not spread maliciously, but it certainly spreads at a very fast pace. A tiny example concerns the engine designations used by Cosworth. I am nearly 70 years old now and my information comes from personal contact with Duckworth, Jack Field, John Lievesley, Brian Hart etc. SCA = Single Cam model A. FVA = Four Valve model A. BDA = Belt Driven model A. DFV = Double Four Valve. I hope this helps. I can assure you all that this is correct. There are many many other bits of incorrect information on this forum but I thought I would start with these bits.
