I checked my repro hood and it has more of a straight angled edge than a notched edge like Mark's pic shows but the hood bumper cups only have 3 welds - so the notch appears to be a good way to confirm a GM hood but maybe not the numbers of welds.
John, Thanks for checking with Badger - I had sent them an email with no reply. I checked with Chambers Chevy and they do have a GM hood. Unfortunately the parts guy there is holding it for his own project. Sounds like a possible conflict of interest. (Ha Ha)
I found a small restoration parts company in Michigan that has one but there price is a bit rich - $1600 plus shipping costs. A salvage company in Washington has one also but they are treating it like Gold and want a substantial sum of money to part with it.
If anyone comes across a reasonably priced GM Cowl Induction Hood (preferrably close to Dallas/Ft. Worth) let me know.
Thanks for everyone's input,
