zzp on right

Shanman

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.

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?
