I can only IMAGINE the price it will go for since they built it so big.
I am fortunate to have a 1962 Bel Air with the aluminum front end and the high rise heads and 2 piece intake with aluminum water pump. I was careful not to say Z11. In all of my research I have learned that no one actually knows how many aluminum front ends were built for 1962. 18 or 20 seems to be the general consensus. All of the cars built were Impalas with the aluminum front ends awittily 409/409 engines and none were built with the well known Z11 engine components. The aluminum fenders I have are stamped with a 2 and a 7. The numbers are not directly side by side however very close which leads me to believe the 2 is for 1962 and the 7 is number 7.
It appears the reason Chevrolet built the 62's at the Flint plant was because they were setting up to build the 63 Z11's and they wanted to make sure they worked out the production problems. The only problem was the inner fender liners. When they put the aluminum into the press the results was a crumpled mess. Mine are very wrinkled and were even welded in a couple of places because of the splits in the aluminum. As best as I can determine there are about 6-7 of the original front ends still existing.
I have learned from several racers including Hayden Proffitt that the entire 62 racing engineering initiative was designed for one reason only and that was to win at Indy in 62. During 62 Chevrolet came out with a variety of specific parts to improve the performance of the 409/409. One was the Special Service Package of parts. The last of the offerings included what is known today as the Z11 heads, intake, valley cover and water pump, camshaft, etc. What is not very well known is that Chevrolet also contracted Carter Carburetor to made a few sets of 750cfm dual 4bbls for this set up. The reason was why would they use the same 3361-3362 carbs with better flowing heads and then increase the cu inches in 63 to 427 and still use the same carbs. Anyway, when Chevrolet determined they had a great set up of engine parts and a light weight package they decided who would get these parts. In my discussion with Hayden Proffitt and additional info to validate this, Chevrolet shipped the parts in 2 kits, one the engine parts and a week or so later the aluminum parts. NHRA would not allow the light weight aluminum parts to be used in Super Stock and changed the classification if the racers used those parts to AF/X. The engine parts were ok. Interesting Hayden shared with me he had been racing for Chevrolet and raced Monday thru Thursday at Lions Drag strip in Calif testing the car. He had written down every combination of jets and metering rod combinations base on temperature, humidity, tire pressure, RPM etc. When he reached Indy in the fall of 1962 he began and waded through all of the entries. The weather changed, clouds moved in, temps changed. He looked up his best combinations, changed the jets and metering rods and went out and out ran everyone. His hard work with the new Chevrolet parts partnered for a fantastic weekend out running everyone. Chevrolets goal had been reached!!!
One small bit of trivia is that all of the engine parts shipped were cast with what is known as "0" parts. These parts were experimental parts and never ever to have left the Experimental Lab. We all know these parts slipped out and all of the pre-Z11 parts ended up being what was shipped to the racers of the day. I am proud to say the Black 1962 Bubbletop I have with the aluminum front end is also equipped with all of the experimental "0" parts including the heads, intake, valley cover, aluminum water pump and exhaust manifold.
I hope this info is of assistance.
I have bent aluminum and had it crack, but if I hit it with a sharp blow, like a hammer, it bent and did not crack. Aluminum boat prop for example.
