Check around your area for an auto shop with a coil spring testing machine. They aren't cheap, so you might not find one...

I think I read somewhere PUSH had one. Might be worth a call too.

any higher end motocross shops near you? take it to them for the above machine.

or redneck way:
stack up weight lifting plates on the spring and measure the distance the spring compresses from static.

Only real way to know is to bring it to a shop that has a spring tester....however, I can probably get you a pretty good approximation if you can give me some measurements (with a set of calipers) and pictures. I would need....spring outside diameter, coil diameter/thickness, free length, and number of coils (or a picture of the spring).

It won't be perfect because I'm going to have to assume a type of spring titanium, but it should be close enough to round to the nearest spring rating.

Sound right for 350?

Using Beta C spring titanium as the material, I am getting 361 lb/in. If you want I can take a picture of the work to show you...but I would say your 350 lb/in is probably correct.
