Question for clipped front guys

[onedayjake]

I have a 1/2 ton 47 with a 70 Nova subframe under the front and have recently went from a 454 to a 5.3. My front springs were a little too heavy for my liking with the big block but now with the 5.3 it's way too stiff. I was thinking of trying
the QA1 coilovers but I've heard of some people having problems with the lower cross shafts breaking and other people say they are just junk in general. Anybody running these? I have no idea what the front of a Camaro or Nova weighs but I've scaled my truck and it was 2200 over the front and 1200 on the rear with the big block and 1900 front, 1100 rear with the 5.3.
