I will oNLY use MELLINGS lifters. I will NEVER use another SEALED POWER hydraulic roller in an aold school VORTEC again. BOTH times I used SEALED POWER I had problems, and both times it was in a 350 with a hydraulic roller cam. AUTOZONE carries MELLINGS, most everybody else carries SEALED POWER. And MELLINGS was the OEM manufacturer for GM for these which is strange considering FEDERAL MOGUL makes many OEM parts.
