Yes, shouldn't have any issues for the most part. Early intakes have thicker intake bolt bosses (~.200" thicker for the short bolts and ~.300" thicker for the long bolts, so roughly 1/4 longer) Early intakes have one piece choke assemblies, later intakes have 2 piece assemblies (early intake has the heat crossover pocket cast in place, later ones have a removable stamped steel piece) Early intakes have the PCV on the passenger side, later intakes have it on the driver side Early intakes have a vacuum port in #6 intake runner towards the passenger side, later intakes have it centered behind the carb Later intakes have a few additional bosses for throttle dashpots/solenoids The intake passages are slightly different between early and late intakes.
When you say Later Intakes, are these the Rover Intakes? Can an Intake Manifold from a 97 Land Rover Disco work with a Buick 215ci ?
It should work fine. That's an EFI intake right? Is it the Federal or the later GEMS setup? I can't remember what year they changed over. The later one has better runners and breathes better. Port match should be very close. Rover also used a very nice sandwich type lifter valley pan, and some simply phenomenal stainless MLS exhaust gaskets that are indefinitely reusable. I'm also a big fan of the Rover cast aluminum valve covers. Jim
Thanks Jim, I found an even better custom EFI setup which I think may be better suited to the Buick motor Im considering, but could use more guidance.
Buick modified the 350 intake manifold, so there's "early" and "late" manifolds, all functionally he same.
