set of 16 made just for buick 455 in 5500 rpm range. Same as what we used to buy 8 years ago set of 16 $71.00 Now I am having Race lifters in Hydralic that are indestructable per testin that will rev 8000 rpm all day long and never fatigue with high spring pressures. These have an extra reserve layer inside for top end and do not use the silly clip like the sealed power made in mexico or the china lifters. These are made from the same people machines and tiollerances for the buick 455 only. Race price $90.00. Shiping is about $10 a set of 16 quanitys limited.I had to purchase 250 to get the race version made.PM me if wanting the best lifter you can buy, chris
