Yeah, when I had the engine rebuilt two years ago, they installed Morel lifters Hyd. rollers. They were always a good lifter, but I heard they are now assembled in US and machined in China. They were very noisy from day one. After two years they were tapping worse and the car sounded like a POS. The old solid rollers were quieter. Then I read all the complaints on the internet. Now everyone says Johnsons are the best. $800.00 for the set but much quieter. My engine builder fought like hell with Morel and got me money back. Live and learn. Morel makes a lot of lifters for some of the cam companies. I heard Isky dropped them due to all the problems. I could have bought Jesel's but $1800.00 was out of my league. I have Jesel roller rockers. Car should ride, handle and run much better.
