bought these replacements from a turbobuick vendor, they are 85 pounders which work great for stock cam and stock installed height, and are brand new in the bag, original springs were only about 78 pounds new from my knowledge, i went with bigger cam and taller springs and retainers on my build for higher lift and rpm range so someone else gets a good buy here, shipped to 48 states for only 40 bucks to your door
