My ("new") engine has been sitting for ~30 years, so I pulled a couple springs (singles with dampeners) and tested them, one that had been compressed all this time and one that had not. Installed height measured at ~1.687, and the uncompressed spring tested out to ~290# at 1.180 (0.507 lift). I don't know what the cam is, but it has ~0.468I/0.507E total lift. Durations could not be checked at this time, but that wouldn't matter on the springs anyhow.
It appears the springs that were in it were Mopar P5249847s, which now seems to be unobtanium and quite potentially discontinued. The popular Comp 901s bind at 1.160, so I can't use those. Now what?
EDIT: I am seeing differing data on the 901 bind height. Still looking...
