I'm not an expert but I suspect with the 4x4 conversion you are under-estimating the final weight.

I'm a torque junkie, I'd put a bigger motor under the hood for a project like this one. At least a 454 and probably something like a 500 Cadillac.

It's true. I really don't do anything but browse the Internet looking for trouble...
