Ok for my application it will probably outlast my motor. Are you talking about LS base crates? I know there is still lots of places that don’t allow LS base engines

No the 602 and 604 crates. Usra allows the ls based 525 crate butonly a handful of people run them. Your springs will last forever i was more saying they were an upgrade. I worded it poorly.

All good I understand.
