Just to let you and others know before you call. These are not cheap, They do not compare in price or quality to anything but the best from Crower and Isky.
These are not Comp Cams or Crane or Cheaper Crower, Herbert, Isky etc . I said they are lower cost than the best from Crower and from Isky, not their cheaper lines. You would use these in applications where it is necessary to buy Isky Red-Zone, Crower Hippo Cut-away, and even the Jesel. If you do not need a top quality lifter to handle excessive spring loads, and are trying to find a cheaper alternative to common streeam lifters, do not consider these. They will handle the spring loads a Jesel or LSM will but are a tie bar lifter. that has internal oiling for the roller and the body is cut-away to help clear pushrods.
