Wow. I am amazed that the reports are still around. Did you get them from BC? Do your reports have the first chassis that Negstadt designed or the latter chassis that Turner and Remington designed?
I came to the same conclusion. If you look on the KMP259 thread you will see that Morris changed his rack, for this very reason. Shortening a stock rack is not too bad on a lathe. It does however increase the minimum turning radius.
Also I believe that some of BC success in tuning his suspension came from following Colin Chapman's theory of "Any suspension will work, so long as you don't let it."
From what Peter Brock has told me I am sure that AC had a ton of steering racks left over from the 289 Cobras, and so the 427 Cobra was stuck with a non optimized rack. Actually it is amazing that Turner and Remington were able to make it work as well as they did...
