Frame Notch...

Yeah, most notches actually increase the strength of the frame. S10Blazed Si has a real nice 7 or 8" step notch on his S10 that he said he felt actually increased the rigidity of the frame. I guess once you add in that box tubing and the full welding around, it has to at the very least increase the strength a little bit.

The stepped notches will definitely increase the strength, especially if you are replacing channel with boxed. Yours will be about the same strength, but you were able to keep the stock floor.
