Thread: PRW FORD FE 427 Roller Rocker set up

Tweet

Couple things.

First is that I have looked at the PRW stuff but decided not to sell it. Just seemed to be a Chinese knock-off of Crane's (RIP) kit. I already sell a bunch of Erson and Dove parts so I did not see the need for yet another in my line-up. I can't say anything good or bad about the PRW parts themselves.

The Inspector was having a rough day. He's normally "spot on" but missed on this topic.

A bronze bushing is a pretty good bearing material and application. That is what's inside of nearly every floating connecting rod. Does not make it mandatory - as a bushing can reduce the section thickness of the arm itself. But the bushing is a good thing and equal to or better than a roller bearing in virtually all applications where oil supply is adequate.

The roller tip at the valve end works pretty darn well. Point contact is perfectly good as a roll couple. Truth be known you cannot physically have any larger contact patch on a roller bearing. You don't get much roller rotation because of the small arc of travel - but uncoupling the rocker arc of travel from the valve tip vertical motion is all that's needed to be successful in that application. You won't gain a single horspower, but the guides will live longer.

Hi,
I sell the Harland Sharp rockers and I have FE shaft rockers in stock. They are the originator of roller rockers and best yet they are MADE IN AMERICA!!!

Hello, You may want to call Steve Tanzi at Erson Cams and ask him if he has any rebuilt roller rockers for your application. He is wonderful to deal with.
If you tell him you read about this on the FE forum you will probably get them for about half price. Make sure you specify if you are using Cast Iron or Edelbrock heads and they will ship assembled correctly for your application. Robb McMackin is the guy who developed these for Erson and is a great person to talk to as well.
