Morel makes 2 different styles of lifters. They make a standard series which sell for about $285.00 and the pressure fed Pro series that sell for about $515.00. We use both as well as the Crane Ultra Pro's. Morel sells their lifters to PBM, Engine Works, Doug Herbert, Lunati, Ruben Cams and many others. Crane lifters are not made by Morel. All are good quality.
