Awhile back I bought an intake from a hummer 6.2 on ebay and it turns out its a single plane manifold. Now, all civilian intakes I've seen have been dual plane. Since I now have one of each, which should I use? I figure since the 6.2 will have plenty of grunt for low end crawling, so I would like whichever manifold gives me a little better top end. This will be on a trail truck BTW.
