Fender sticker reads 402.
I believe the owner's manual reads 402.
SPID reads 400.
Emblems read 400.
Small and Big block 400 are both referenced as 6.6 liter (rounded).

The info. is all over the map.

Speak of SPID, anyone recommend a clear cover for these? Mine started a peal at the corner. I think it may be able to peal the old one off w/o damaging the SPID (maybe). Otherwise I suppose I could cut the edges, apply a second cover on top.
