LS7 valve spring specs Hello,
I've been getting some inqiries about LS7 springs to fit (or not) certain aftermarket cam lobes requirements.
These are the LS7 spring pressure specs to give you an idea of whether they would be capable of handling the cam.
As we know it is not only the lift that affects that decision but more precisely the seat/open pressure capability of the spring.
Valve Springs - Free Length
58.8 mm
2.313 in
Valve Springs - Installed Height
49.75 mm
1.959 in
Valve Springs - Load - Closed
450 N at 49.75 mm
101 lb at 1.96 in
Valve Springs - Load - Open
1380 N at 34.75 mm
310 lb at 1.37 in
Coilbind is 1.085 in
