Default LT4 intake?

I have a intake that has red paint peeling from it. How can I tell if its a LT 4.
I don't think it is but it would be nice to know.
thanks in advance.

On the passenger side flange near the 3rd sparkplug port there is an 8 digit number.

What's the number on your intake?

Lt4 intake part numbers

Part Numbers at a glance-

LT4 Grand Sport - 12550630
LT4 Conversion - 12550631
LT1 Stock - 10108630

LT4 Intake Manifold part numbers PLUS Stock LT1 Manifolds - Auto-Trend Repairs and Service Information Forums

The only difference betwean the LT4 intake and the 1996-97 LT1 intakes is the material above the ports (and the part number).
