EGR passages under the plenum
Why does a 86 have two passages yet a 91 doesn't?

Yeah maybe hey. Do you need to know for a reason or are just curious?
I have a homemade billet egr block off plate that frees up a bit of clutter from that area... easy to make and looks neat.
Also JProz1167, i noticed in your profile that you are unsure of your Vettes rearend ratio. Is this still the case? If so, you know how to check it by rotating the rear tyres?
