Stock springs are real close to the specs for the crower springs most poncho guys run.
Used springs wont be though...LOL
I used crower 68404 springs on my build. I am running a crane 272-2 .
Those springs would be plenty for the cam OP suggested.
I am running them on a cam with .480 on the exhaust. Over the nose pressure was 278 lbs. on the exhaust.
Pressure at installed height was around 125 lbs IIRC
Fact is stranger than Fiction
