[QUOTE="Walt Jaquith, post: 426293, member: 18654"] There's actually some reasoning there. They went with port fuel injection instead of the cheaper and easier throttle body injection that everyone else was using at the time because with a straight six it's impossible to get the runners to each cylinder the same length, and with fuel suspended in the air, that makes for really uneven performance between the cylinders. Even with just air, it's important to smooth out the pulses and turbulence between the cylinders. If you look at the intake manifold of a modern rig, even the V6s and V8s do the same thing. They look a little more elegant, but they have a main chamber that the air comes into, and all the runners for the cylinders are the same length and shape. Given the year it was designed, it's possible that the Jeep's intake manifold was designed on a drafting board. Not so easy to do something with a bunch of swoopy shapes.
