has anyone ever tested if all the intake manifolds flow the same ( fiero intake for 2.8/at least the upper part is different///////regular 2.8 manifold////3.4 manifold)

just wondering if anyone knows/thinks the little design differences make a difference

 

from what i remember hearing, the 2.8/3.1 intake flows better than the 3.4. or maybe its just that it has more potential to out flow the 3.4 since it is easier to port. i just remember reading something on here about that.

 

Thats pretty much what I have heard with the differences between the intakes.

is ther any difference with the fiero ones? are just the tops different,,,,,,,,,,,not the fiero ones that say fiero,,,,just the square top ones,,,,,,,,,,,,,,,,,,,,,like the one in this link

I'm pretty sure that it can be mounted facing the other direction. Though dizzy clearance might be an issue at that point.

But agreed, if an improvment is being sought after, I'd look elsewhere.
