help identifying a couple of parts please?

[AnthonyS]

Hi Gang, found some parts and wanted to know if anyone can assist in identifying...

first is a chrome single snorkel air cleaner lid - stamped "front" on top.

second is a trap door oil pan - not sure it's SBC and it's been extended / welded to create a deep sump, not unlike the GM Performance OTC BBC pans that we've all seen (3879633). Driver side dip stick. Is this a SBC pan? The bolt pattern looks different, there's reinforcements in each corner. Is it a GM pan / is it aftermarket or a modified pan / one of a kind. Looks almost homemade too. That windage tray was found with it.

Any help is appreciated of course.

Thanks everyone!
Anthony
