Good Info & advise above.........
Nice combo, plenty of HP & Torque to put you in the 10.0, upper 9s bracket range. Weight will be in the 3050 - 3100lb range + driver. Like Actionange said keep it simple. You want low maintenance and consistancy with any choice you make for a bracket motor...from what I have seen...W8s and their high RPM operating requirements tend to be on the more expensive side to maintain.
I would recommend that you give Ryan Johnson at Shady Dell a call...One of the best guys out there when it comes to SB Mopars.
