Does this LT5 have a prototype plenum? - ZR-1 Net Registry Forums

Came across this auction today on eBay.

Looks like it has a prototype plenum on it as the pipes on both sides are all metal with no rubber parts. Also, PCV pipe from the TB to the PCV valves is some kind of weird black pipe that doesn't have the tabs to mount to the plenum. Wonder if that LT5 could be a really late prototype that was just before the production ones? Would be interesting to know what the VIN stamp says.

And the guy thinks it's a '95 LT5 (claims it came out of a '95 ZR-1), which it clearly isn't if the cam cover emblems are the originals. Looks like a '90 LT5. I sent him a message letting him know.
