67 Impala rear coil springs

Will heavy duty rear coil springs for a 67 Impala raise the body height?

On summit racing, I found Moog rear springs that are 17.10 inches high with no load and 12.5 inches under 1500 lbs. I am not sure what the stock doing height is though.

Define HD. Springs work off of weight. They compress under weight and expand as the weight is removed (think The General Lee in the middle of a jump).

To get your ride height correct (this could be factory specified, or what you want it to look like) you have to buy a spring with the correct spring rate (inches of compression per pounds of weight) that starts off with the correct free height (unloaded height) and has the wire diameter need for a smooth or firm ride (this is subjective) with the correct pig tail, square or tapered cut wire to fit in your car. Moog sells thousands of springs, hundreds might fit your car but only ten or so will meet your needs. I suggest you find out what your car weight is (four corner scalews are the best) first then call for help in selecting your spring from whomever you buy it from.

Thanks for the info. I'll research it in the warmer weather.
