Re: Intake Manafold

Check the 4 center intake bolt angles, they changed on the 87 up f body intakes.

Re: Intake Manafold

Identical. Just the above-mentioned differences between the 86-down and 87-up manifolds in bolt pattern. Also, I don't recall when they did away with the 9th injector, but I think the lower intake might be different on earlier engines that used a 9th injector vs. later ones that didn't. I'm sure somebody will chime in and clear up the 9th injector issue shortly.
