what do you guys think about this cam rec

Looks good to me. Mark and Tim are a couple of the sharpest guys at specing cams out there. Keep in mind that solid cam duration @ 0.50 numbers are around 8* - 10* larger than a equivalent hyd. This would be like running a 230ish hyd cam. The lift will also be around .500 after lash, deflection, and the SB Mopar angle loss. As with all motors you will need to check/measure everything.
