As the title suggests, I replaced my Stage 1 front springs several years ago. It didn't lift the front end at all but it did have the same height without a couple of twist-in spacers in the old springs. My question relates to the fact my 350 car has a couple of twist-ins in the front end and if my old Stage 1 springs, being for the heavier car, would be any better than the sagging 350 springs? I'm not so cheap as to not buy new springs if that's what it takes but I have the original big block springs sitting in my garage attic. I figure they should be good for a bit of extra height. I figured 50-year-old 455+400turbo springs are at least a few 100 lbs stouter than the 350+4 speed springs.
I think you should trade me for my 40,000 mile 350 springs, for your BB springs and we’ll both be happy. Shipping $50 for us, better than the $200 for new.
My car has the original 350 front springs in it. They are working fine with the 470, and were also fine with the all iron 430. I wouldn't sweat it. I'd put them in.
