Re: Boxed frame vs AFW for \'74, strength differences?

I take that as a miss type then Taz you mean you "wouldn't touch one" correct?

I'm not sure what you are doing exactly, but I suspect you are doing some good. Hot rodders boxed frames for years and it was a good thing, of course a new frame is better but they weren't available at the time.
As to the overbuilding, the frame gets to be a lot heavier weight wise than it needs to be and it gets too rigid, not allowing any frame flex. To demonstrate the latter, while I was working at the GM Leeds Plant, a body shop foreman's new car came through on the line. He had it pulled into a repair hole and they double welded it, putting a weld between each existing spot weld. His Monte Carlo rode worse than the typical Jeep. Because he bought it through the Class A employee plan, he had to keep it 6 months. The day the 6 months was up, that car was gone.
If you've got the time, the patience and the means, go for it. What could you loose? For strength, the pieces you box it in with are best if they are a continuous piece from end to end but putting in a few plates, even only an inch wide, at various places would improve the stock frame. Naturally, using a continuous section from end to end means cutting all the cross members loose and having to square the frame when you weld them back in, probably something you don't want to do.
One word of caution, don't make long continuous welds, you'll warp the frame. If you have a way to clamp the frame down, that is good, but it will still be warped if you weld wrong. I'd stitch weld the whole thing and then go back and weld a little here and then a little over there, a little on the top and a little on the bottom.
