Figuring out what springs to use

I'm in the process of putting together my little hot rod or whatever you want to call it. I ended up using a nova front end clip on it in order to get a cheap independent front suspension.. The car the clip came off of was a 76' 4 door nova with a 350.. My problem seems to be now theres nowhere near enough weight to compress the springs to a normal ride height. As my upper control arms are hitting on the bump stop.. i'm sure the springs are a little too stiff.. The issue i'm having now is how do you go about figuring out what spring rate you need to get in order for it to sit correct?

My guess is the whole truck will weigh in at about 2500ish.. I believe the nova for that year was around 4000 for the curb weight.. I was considering cutting the spring in order to lower it but i'm sorta worried about how stiff the front end will be then..

What we need is the axle weights on that car..You can look around and find a company that has a certified scale.Iuse the local gravel pit..Once you have the weights then Speedway Motors has a chart to help select a spring that will work..Circle track racers have scales as well if you know any of those guys..

You need the car weights to figure out the spring rate. If the current springs are to stiff you don't want to cut them down, it will only make them stiffer....

If you are on a tight budget and don't expect it to ride like a Cadillac you can cut the springs.Yes it will stiffen the ride but it will lower the truck. Cut 1 coil off at a time and try it. Remember to roll the truck back and forth a little once you put the weight back on it or you won't see the real ride hight.If you have to cut more than 2 coils it will be too stiff.After the first coil if it needs to go lower cut 1/2 coil at a time.Hope this helps.No it won't be the best ride but it is free and it will work.
