MANLEY NEXTEK 22-1448-16 VALVE SPRINGS USED

I have a dozen or so boxes of Manley Nextek and similar Pac 1448 valve springs.  I have tested a couple of boxes and they vary from 380-410# @ 2.050".  I haven't checked every set and they are sold for a paltry 50 dollars per set.  These are a 1.667" dia. triple valve spring and are common to a vast number of billet 426 hemi fuel heads.   Won't last long, call 402-+597-3242 to get yours on their way.
