Need to make a decision fast 5.7/6.1/340

I have spare LX manifolds. If you want to try those, I will send them to you; just pay shipping. I would think the jeep ones are too long. If you are mounting them upside down, a set of shorty truck headers may be ideal, but I don't actually know.

I am not doing the swap. Just was curious is all. I think there are a few threads about this subject on either YB or Theturboforums.
