Who is looking at a cam swap?
At a glance, Comp Cams Hemi Phaser "274" Camshaft for VVT 5.7L looks to be a solid contender for a cam swap.
Some threads I've read say that the test vehicle had aftermarket valve springs and a larger throttle body, while some do not mention these mods.
From what I've read, it looks like HHP has to tune in person. This requires that you fly their tuner out to your location, or you take the truck to them.
On the safe side, you'll need cam, phaser lock/limiter, springs, tune, and installation of course. ($3000-4000)
Only a few guys have this cam, and some have mentioned that tuning has been an issue.
Does anybody have any info to add?
