Sorry, but all hydraulics aside, I would go with the solid mopar .557" cam...I run it, my engine builder runs it, and so do many others for these 408/416 combos. Great idle, awesome mid range, and pulls hard on top even in heavier cars. Not to mention it sounds awesome at WOT.... Only problem with your combo is the crappy carb. Get a good Quick Fuel or other 750-950 that flows well. You could get an annular 950, and it will run with the big dogs.
