Anyone using beehive valve springs on a slant-6?
Surely can't be that easy - can it? Even the threads Dan notes seem as though they are still fiddling around with the right combo of parts and everyone seems NOT to be using Mopar springs. Would you by chance have any part numbers? I sure would be grateful...
BTW - took another look at the Hot Rod article - good stuff with some details worth banking. Thanks for the reminder.
Slantys and SBs have the same installed height and retainers/keepers, it is as simple as that, all the springs Mopar recommended w/the Purple Shaft cams for the slanty
were SB springs. I was running the Red 340-HP singles w/dampers on Mine. As far as optimal/perfect, well, there is almost no such thing. But I haven't had a single issue
with Mopar's valvesprings that weren't caused by improper installation/application. Had a 340 6bbl turning 7200 routinely on the P3614542 dual springs w/dampers, 383
turning 6500 the same on the Green stripe Hemi singles w/dampers, I had 1.74/1.41 valves in My slanty and those P4120249 Red 340 springs, went waaaay above the
operating range on that engine(unwisely :D) and zero problems. Of course, those were springs made & purchased over a decade ago, hope there isn't some new "issue"
with current ones. I haven't heard of any....... The upshot is, any beehive suitable for that installed height & cam spec will work w/the correct retainers & keepers.
