The cutlass isn't a regal, but it's a g body so hopefully I can get some advice. I have an all iron 455 in it, and I'd like the nose to sit 1-2" higher. I know the 455 is lighter than a bbc, but heavier than a sbc, which the car came with. I would buy stock replacements, expecting some sag out of the originals, but doing that out back got me nothing. Nobody online seems to have a straight answer for this, as they all want to go lower. If anybody knows of/has used any particular spring for this I'd like to know the part number, thanks!
Go to scale weigh front tires only. Record weight. Regular height of spring on g body is 11 inches. Get a spring any size over 11 inches that compresses to 11 inched that also matches the weight of the front of you car. They have many from moog for the g body and s10 google up a spring load chart.
I'm running Moroso 47205. They are for 1660-1720 front weight. My car with aluminum headed and intake buick 455 is 1688 . It seems to work great on street. Looking at track numbers in a few weeks. Front end sits a little lower than stock and rides great
