I'm doing a 5.4L 4v build and am looking to use a Cobra Jet intake manifold since MMR came out with some adapter plates for Navigator heads. Intake manifold choices for these heads are slim to none, but I really like the look of the CJ intake manifold and it looks to stand just high enough to clear the alternator on a 5.4 DOHC motor.
So how much air has anyone crammed into these composite intake manifolds?
