Any difference between 2WD and 4x4 plenum chambers???
Is there any difference between 2wd and 4wd plenum chambers?
I know the later EEC escort ones are different but were they changed on the weber equiped cars?
If so, what are the differences?

Well I'm hoping for around 450hp, I did read something MikeR put about not over speccing stuff.
He said that the 4x4 setup was better for around that h/p then anymore you would want the eec iv.
I presume there is nothing useable from the 2wd manifold if I went down the route of using either of the other manifolds ?

The difference is in the throttle elbow and thats where the restriction comes from. You can open this up by having a plate welded on the outside and cutting away the rest, this with a plenum spacer and its good for over 500bhp.
Escort ST one is good if dont want more than 480bhp, trying to find one is the fun part though.
