I think the 400 is a great motor if you shoot for torque and put a torquey cam in it. When it all goes bad is when guys try to make "horsepower" motors out of them and overcam them and spin them too high.

I'd think a 400 block with 1.94 heads and a 204/208 cam would be great street truck!

But higher RPMs are not it's thing. The rods are so short relative to the stroke that they barely reach the crank when the piston is at TDC ;-)
