Z28 valve springs
Can anyone give me some vital information on these valve springs.
Whats there max lift, are they single or double. Are they worth the money?
They will be going on a valve that has a cam lift of .488
Thanks
John
No they aren't going on my 408.

they are a single spring with dampner and I believe they are spec'd to about .500 but can be pushed to around .510 and I think they have around 110lbs closed. best thing is they're cheaper than hell. I got mine from a machine shop for a little over 16 bucks for a set!
