Details:

It has a date of 12-12-68 on it. No plugs, no repairs, threads and holes are excellent. This intake is in very good original condition as shown. It came off of a 1969 big block Camaro.

I can't say its NOS but close. Intake is not painted. This intake is a very nice original part that has been in storage since the early 70's. For sale is an original OEM GM intake.

This is a very nice unmolested 163 Intake. There are no breaks, repairs, or modifications.
