I need some input regarding the use of roller rockers on a race prepared TR6. If you are running a cam with .500 lift and 300 degrees duration, does the use of a higher ration roller rocker (1.65) r

Not that I'm trying to tell you how to suck eggs, but the primary reasons for using roller rockers are to decrease side thrust on the valve stems, reduce friction in the valve train (pin bearing in t

That being said, the dyno tests involved a fully developed race engine run with stock rockers and again with roller rockers. The difference was 2 h.p. - maybe a 1-2% difference overall. Hardly close

While everyone seems obsessed with lift, the real secrets guarded by cam is the interaction between duration and lobe center angles. Then you need to figure out how they interact with lift. Look at:

Not to flog a dead horse further, but there are two different things going on here, lumped together as "roller rockers". 1. The interface of the rocker tip to the valve. 2. The rocker ratio. They bot

Got it. I think what both Jack and the test I referred to found, was that head flow was the limiting factor at least for Triumphs. V8's are certainly another story. I'm running a fully ported head w

Allen, Bill B.is correct. The big advantage to roller rockers is reduction of valve stem/valve guide wear. High ratio rockers for your car - 1.65 - greatly increase valve train strain and wear. Even
