I'm trying to find some information on these valve springs. I've got a seller on ebay pushing these as made specifically for blower/nitrous applications. I can't find them on the Crane website. Does anyone have any information on these? Seat pressure, max lift, max rpm, etc? Will they work on an NA application?

Thanks.

Not sure about these particular springs. However, I do have a new set of Crane dual valve springs (pn-99893-16) for sale for $85.00, shipped. These are good to at least .600" lift, work well w/ NO2 or n/a, and require no head machine to seat properly. Hope this helps!

HA, HA! Thanks fastcam. Way to make a quick sale! That's a good price for the springs.

Right now I'm just gathering parts slowly for mass instalation in mid/late summer. The springs I asked about a put of a package deal. Was trying to find some information on them to see if they would meet my application.

I'll pass on the springs for now. You shouldn't have a problem selling them.
