Franz:
Fred Gamble reports that they were on #2272 when delivered; removed (and lost) at Le Mans when Fred observed "These are for cooling the shoes, right? We have the Mulsanne straight to cool the brakes.". To the endurance racer, they were just 4 more items where something could go wrong.Comment

I don't recognize it as a drawing I received, but would like a copy. If you're looking for other things dealing with the Cunningham Le Mans cars, let me know. I have copies of many of the work orders, and there were a lot of them.
In talking with John Fitch, he confirmed that Briggs at least started out thinking that they could do enough to the cars that he might have a real chance at his dream - an American winning Le Mans in an American car.
The difference with Casner was that the Corvettes were part of PR as an American team, but Lucky knew that if Camoradi won, it would be with the Birdcages. Camoradi still had full access and received items like the hood air deflector (that was mounted in a different location by Lee Lilley),
but the two cars were basically bone stock FI/HD brake cars with the 24 gallon tank as delivered. The Big tank came later.
The difference also showed up in the driving; one of Casner's main problems was caused by the reputations of his drivers; Star #1 goes out first; the change is made and Star #2 goes out, with his main interest being to be quicker than #1's best lap. In one case, the transmission in the 'cage gave out when the car had a 7 LAP lead. In the Corvette at Le Mans, Gamble's instructions were "All shifts at 5000 RPM. 5700 RPM maximum on the Mulsanne, with two lifts to breathe the engine.".Comment

Re: 684/687 Estimated Fan Production Date
Hi all,
On the subject of BB fans, I have an interesting set that have the fins angled, so as to better direct cool air. Each side's angles are a mirror image of the other. I bought the setup from a guy who, in 1969 as a kid with his dad, salvaged the BB pieces off what he thought was a 684 1959, but more likely a 687 '60, in a junkyard in NC. His father didn't want to take the tank because he thought no one would want it since it would prevent use of a convertible top! Meaning a 24-gallon one! It must have been extensively raced seeing that the A-arm shaft holes were worn into ovals.
Anyone seen angled fins like this before? Or did the racer just bend them on his own for better cooling? Some other questions:
And perhaps someone knows what sort of front coil spring this was on the same Corvette? Here is a pic of it compared with a HD 140 coil used 1957-59. It has at least three more coils, but the coils are a thinner gauge. Perhaps this gave the same effect? A bit of green paint daubs remain on the third and fourth coil from the bottom if that give a clue.
One of the coil springs had an aluminum shim. Has anyone seen this type of shim before?
The front shocks were spirals with p/n 5519443 dated 6 C 53. Was this a heavier duty shock that they might have used in lieu of the 684 ones?

With regard to your front spring. The blueprint notes: Springs not requiring a shim to be ID by dot of white paint on second coil from top. .06 short with 1 shim #3694719 to be ID by dot green paint. .12 short with 2 shims 3694719 to be ID by dot of yellow paintComment
