A block of wood cut to the right length would make a much easier temporary "spring". Never heat a spring.

As long as you cut it with a cut off wheel and not a torch it should be fine. I have done several that way. You also want to use a 90* sander to reshape it so it sits in the socket correctly. Cutting a coil will also make it stiffer ( they are torsion bars that are coiled, basicly) the bouncy mentioned may have been from weak shocks not being able to control the stiffer spring. I've never had that result. DO NOT USE A TORCH, and DO NOT QUENCH IT with water, you'll make a weak point that will snap off on the first bounce...I know, that's why I only use a cut off wheel. Fortunately the torched spring was in a race car I was building and snapped with no engine in it,while I was bouncing it...could have been a hell of a ride

Thanks guys, I just don't see how the spring will sit in the seat. The end of the spring is wound into a tighter circumference and the seat is shaped to match. It would be a good thing if the spring ended up stiffer, as it's a large car spring going into an F100. Like I said, unless it really works well, I'll be getting different springs down the road.

There is no air conditioning, so the absence of the added weight of an air conditioning system (probably 100 lbs) makes the car sit an inch or two high.

Anyway, I'm doing a front brake conversion soon (drum to disc) and the front springs need to be compressed, and possibly removed anyway, so he says "lets cut the front springs". I told him I heard that is a bad idea, and changes the shape of the end of the spring so it won't seat correctly in the spring pocket. Then, there is always that potential problem of the car sitting to low after they've been cut, and then I'm screwed. He said "I've done it several times and never had a problem"

This is a 600 HP 72 chevy nova - street car.

what do you guys think?

Take the big block springs out when you do your disc brake job and sell them to someone who needs them. Put small block springs back in the car when you go together with it. The big block less the AC weighs about the same as a small block anyway. If you cut the big block springs, you will change the spring rate and I predict severe unhappiness in your future. Been there, done that. Never again.

Dont cut or replace

You have a big block.Dont look at your car for a while.That big block will settle the springs after yoy get some miles on it.If you cut or shorten the springs your ride height will go away sooner than you want.Leave it alone go drive it for awhile it will all work its self out.

if the small block springs were to soft and the big block is too much check out the specs of HD small block springs. I got some for my malibu for around 90 bucks about 5 years ago.

Springs

You are right.The hd springs will work.But he already has the springs in the car and To keep from doing any more work or spending money the springs he has will work.They just need time to settle down.
