I remember SOMEONE making clear Lexan valve covers maybe 25 years ago. I haven't seen them since.
It might have been small block Chevy only. Maybe?
I think they were made for racing purposes? Drag racing primarily. This way you could visually check for issues on a running engine without tearing it down.
Wow, that's a memory test for sure. Who the heck made these things?

I want to say it was one of the large camshaft companies. Check ebay. Maybe a lead will turn up there?
