Hey guys, Im still learning the good stuff to buy for ls1's, So I need some help with buying some valve springs. I have a zr1 cam im putting in a turbo car, What is a good brand spring to run?

 

PAC springs

Thats what ive heard. Thanks jay lt4

 

I hope to like comp cam springs. They use a different type of steel or something that wont lose elasticity as quickly. However, if they do decided to crap out they usually will break rather than tire, but if shimmed properly I've heard good things about their longevity. PRC's and Patriots have done nothing but wear out quickly for us, so we just decided to try comp in a car we have out, however, the car isn't finished yet so I can't say much about it yet, just hearsay from guys who have run them.
