Mooch is getting a little rough around the edges body wise but he's plenty stout in the drivetrain department. Under the hood there's a stroker 489 full roller with Edelbrock top end, NV4500 with 12" dual disk clutch, NP205 with the coupler eliminated, D60/14bolt combo with four wheel disks, 4.11's and a Grizzly locker on 33"s. The motor puts out over 600lb/ft of torque. Heaviest I've rolled over the scales was 19,890lbs with a toy hauler.
