The firing order of a engine is the direct result of the crankshaft design. Last time I compaired the throws of a Chevy to a FE several years ago they did not match up. There is some torque advantages and disadvantages to be had by verying the firing order of a engine. Ford took advantage of that with FE's and thats why they were competitive in forms of racing that required more or less constant RPM ranges. Ever wonder why FE's had so many types of heads? With hind-site, the answer is they couldn't get it right, at least by current head thinking. Don't get me wrong, I'm not bashing FE's, cause I love them to death. But there really is a reason they don't make them anymore. They were made from 57 to the early 70's. When you look at 460's being made from 67 up to the presant that has to tell you something. Come to think of it, the unbalanced firing orders of current racing engine thinking should tell me something to. One only has to look a V-10 Viper to conclude that we have came full circle.
