Solid Mechanical Roller Lifters

[Ty Kwaiser]

Thank you Alan, Carl, Larry and Jeff for the replies. So I am not certain where the objective evidence lies in "bushed makes less power" but one thing I am concerned with regarding a larger surface contact area with a bushed lifter versus needle rollers is the oil wedge to lubricate the wheel on the shaft. I like thinner oil and low drag oil pumps so I will probably continue with needle rollers. I will likely go with Morel from now on. Regarding the other thread about lighter being better, I have read some data collected on a Spintron analysis suggesting that may be the way to go. Thanks guys.
