Help me sort my combo

Even with 10:1 that's a LOTTA cam. A LOTTA no cylinder pressure building cam. As for cam I kinda like this one:

RB & B Series Mopar Hydraulic Lifter Camshaft

Honestly though, you need more gear than just a 3.55. I have been trying to figure out for years why that gear is so coveted among the Mopar fold. It's the best of nothing. I would use either a 3.91 or 4.10. Now, if you make the gear change, you might look at this cam instead:

RB & B Series Mopar Hydraulic Lifter Camshaft

Even with the smaller cam, I would still recommend the gear change.
