I know you've been here a long time (although I didn't know you were a driving force for this section); I was teasing!!!
There have been a number of SB covers.
Edelbrock curved script (pretty rare)
late model Edelbrock (the blocky ones)
the new Edelbrocks
The stock style chrome
The flat chrome
The Gold and Blue DC style
Morosos
M/T
late model MP
new fabbed aluminum
Cal Custom (?)
Holley (Like the M/T)
Most have been shown here and elsewhere.
I haven't seen any others I can remember.
