Valve spring specs needed
I'm working on a 95 3.6. Does anyone have the valve spring specs so that I can check them?
I have a valve spring measuring scale but I could not find any specs in the service manual. Any help appreciated....

I would be very interested too, I installed the http://www.drcamshafts.com/ springs and he lists a nice table for his spring rates per inch. But that does not help you..

Perhaps if someone has a new spring that they can check and post the results....

They should be around 55 to 65 at the installed height depending on application. Measure them all, they should be within 5% or so from one another.

Thanks, they are all within 2 pounds of each other. I have 70 lbs on the exhaust and 63 on the intake. (intake and exhaust have different assembled height specs)

That looks good. Judging by the spring rates, I am assuming thats due to the hydraulic rockers?
