Did GM make an aluminum version of their stock intake for the 472,500?? I had no idea...how rare are these? And would it work with my 1975 fleetwood?? Any benefits besides weight savings??

Interesting and strange; I didn't realize the 472 had a different firing order than other GM V8's and it looks like the cylinders are numbered differently too. It's been a long time since I worked on my old 472.

This is a rip off.. the intake is off a 1980 368 motor... it will bolt on a 472-500, but the runners are almost half the size of the stock intake.. don't be fooled by these...

I'm glad you cleared that up, I was racking my brain trying to figure this out.
