pressure specs for valve spring

MP 3690933

thanks

Don't have the spec's but the Mopar part number is: P3690933.
Not MP 3690933 which may be a jobber used number.

P3690933 1.83"/1.86" Single/Damper 1.53" 0.224" 0.440"/0.500" Chrome
Vandium

From the mp catalog. The mp engine secrets should have the pressures.

I think that spring is 110lbs at 1.860 but I
will have to check. Good for hydraulic street
cam.

115lbs at 2" checking height
310lbs at 1.50"

Install at 1.83" to 1.86"

That part number does not exist in Chrysler's computer system. Maybe it did at one time, long ago, but not now.
