Well ones ZZP's 82#spring and the other Jbody performance's unknown specs spring lets see who knows their springs...

 

zzp on right

 

On a side note if anyone wants any Jbody springs to test the spring rate I will ship it to you at cost as long as you post specs of the springs on this thread, I have 16 and no plans of doing anything with them. So Yes if you have a valve spring pressure measurment device or willing to have them tested; then FREE JBPerformance valve springs you pay shipping.

 

They don't give you a spec......?

 

I've been in need of some valve springs for a while now. I bet I can take them to my local hot rod shop to get measured for you. I'll take them if the offer stands.

 

don't waste your time with those you would be better off with a fresh set of stock valve springs

 

Do you know of someone who ran these with bad results?

 

I do not know of anything good ever coming out of jbody

 

Listen to mrb
Ive been on here 3+ years and in that time not one person has had a good thing to say about that company their products or their customer service.

 

I'm not planning to use them in the Redline. I wanna get Supertechs for that car.

 

Good choice!
