I don't know who you are yet. Eventually I will figure it out.
Parts availability for FE stuff has been pretty much off a train wreck for a couple years now. As soon as we get a quantity of something in everybody finds out about it, we sell it out in hours, and can't get replacements for days, weeks, or even months. In this past year at one time or another I have been unable to get needed pistons, intakes, heads, cranks, rods, and even cams delivered on time. The suppliers have all cut way, way back on manufacturing capability and staff and cannot meet their own stated manufacturing lead times or promise dates.
But If you really ordered an Edelbrock intake odds are you'd have had it quickly because Edelbrock still inventories stuff. You probably ordered something else - maybe a Dove dual quad tunnel wedge? Dove ships parts when they have them, but they have been out of parts a lot lately and have missed delivery target dates as a result of some employee issues. That's the only place I can imagine subbing in a Blue Thunder part for anything else - would never have done that for an Edelbrock part.
As far as credit stuff - if you had the order number all you'd have needed to do was provide the card number & I would refund the transaction if nothing had been shipped. Lord knows I have done a lot of refunds over the years even when the "date" was long past. (I did have one guy want to get warrantee coverage on a 700+ horsepower engine four years later - even I have some limits). If it was something big or complicated it may take me a couple days to process - money has always been tight as I try to grow the business and I am only one guy...but I really do try to make things "right" for people...
Your name might help - or your order number if you don't want anybody to know who you are.
