Edelbrock/Eibach springs

Does anyone here know the spring rates of the Edelbrock/Eibach progressive coil springs for 67-70 mustangs?
They offer a small block and a big block version.

I asked them and they said to check with Eibach....

I haven't done it yet, as they don't have an email address

Eibach just said "ask Edelbrock" and that it is a proprietary spring, so all info must come from edelbrock.

Mmm, maybe there are better informed people at Edelbrock. Can you post the info you get here? I'd be interested too.

I could also use the info since that is the spring I am supposed to run and the ones I have now seem to be smashing my lifters to death.

Has anyone used the SB Edelbrock / Eibach springs? Are they progressive rate spring? Feedback is appreciated. It seems that they have a very wide tolerance range on the force, I wonder if the numbers are correct?
