Question intake manifold - 1979 Olds 403

Are you looking for a specific casting# and/or date? I have a couple of 403 Olds intakes. Thanks, Bob.

I’m actually looking for pictures of one. Believe mine might not be OEM for a 6.6 liter 79 Trans Am. With A/C. Cannot see where the DS-TVS switch screws into the intake…

Wonder if these links could help you?

Near as I can tell, the intake is casting p/n 411990.
