Both CompCams & Crane make solid roller lifters for AMC. Crane also makes hydraulic roller lifters & cams, but aren't in the catalog(special order). The AMC lifter diameter is .904, but a Chrysler lifter is different. The oil feed hole/groove is in a different location. It would probably work in a stock engine, but with a higher lift cam, oiling to the top end may be compromised. Also, while the ratio is the same, a 1.6 SBC roller rocker is NOT the same as one actually made for an AMC. The ratio isn't the problem, it's the distance from the fulcrum to the valve tip. The SBC rocker is shorter. They'll move the valves, but the geometry is WAY off. Roller cam set-up are very expensive, & bring up a bunch of new problems....mainly a way to control cam walk. Not impossible to do, just more work to add to the project.
