"Part # 10212811
Spring Type: Single spring. Outside diameter: 1.25". Pressure @ installed height: 80# @ 1.70". Solid height: 1.20". Average Rate (lbs@in): 256. Retainer P/N: 10241744. Valve Seal Kit P/N: N/A. CT350/350, 350HO engines"

Not much of a spring for anything more than a street car from the specs shown. A performance type stock spring like the old Z/28 type had about 105lbs on the seat.....80 is very close to stock non performance stuff.
