Thanks for setting me straight Cal. I think you're probably right on the money that the aerodynamics would be the deciding factor. LeMans racing is probably responsible for some of the sliperiest closed wheel cars racing.

If GM were backing the GS team I wonder why they pulled the pin?

The drum brakes was in reference to the production Corvettes racing the 289 Cobras. I read a Road & Track article from June 1963 that had some insight into the Corvette Cobra battle. There is a book of the Road and Track articles from 1962-1983 covering Shelbys and Ford GT40s. It's got some very interesting reading in it and a lot of old pictures. The ISBN number is 0 946489 36 X if anyone wants to find it on Amazon.

Cheers
