The frame will do fine if engine power and tire size are both reasonable. One has to be careful with frame boxing as the flexible "C" channel frame will crack where it meets the rigid boxed area unless the boxing plates have long tapered ends to give a transition from rigid to flexible. The factory S10 box frame had a parabola or Nike shaped "swoosh" to do the transition where the front box section joins the "C" channel rear section. One just has to match the torque (horsepower means NOTHING) to tire traction to figure the stress on a frame. Driving style figures in but the biggest contributor is experience---much by trial and error and a stack of broken parts.
