Maybe, I'm not sure. I was told by others they are an old set of Morels but no way to verify that. There are no markings on them and I don't have the original box anymore. Those (the short set with the enclosed wheel) came out of a 455 I built for dad about 20 years ago? He ran that engine for about 5 years, thousands of street miles and lots of racing, up until it snapped an oil pump shaft. So we saved the cam and those lifters, they were always as quiet as a mouse.

Maybe they are Johnsons but I have no way of knowing. I do know for certain they are from Comp and came with the custom Comp hydraulic roller cam that was purchased through Kauffman.

ever check the cam shaft end play? too much lateral movement will destroy a roller lifter in short order
