Rhoads lifters

Oil has nothing to do with how Rhoads lifters pump up. They rely strictly on engine RPM.

That said, I've always looked at them as a "band aid" for over camming an engine. The only exception is their new VMax lifters. They are truly a different breed. But all in all, as long as you make the proper cam choice to begin with, the Rhoads lifters will not be necessary.

I might have agreed with this until i ran a set with an automatic. These let you cam the engine heavy and still have tractable idle for accessories like auto and AC. I am building a 4 speed 383 car with ac now and chose rhoads lifters to tone down the idle to make it easier to drive on the street. I love the way it smoothly builds power as it all comes back by 3000 or so. Late model cars accomplish this with roller cams that can use a much steeper cam lobe to keep idle good. Rhoads lifters give engine builders roller cam type impact at a fraction of the cost.
