Re: Roller rocker issue

Small lift in cam and high ratio rockers vs. high lift cam and low ratio rockers

Some thinking related to issue.

- There are limitatios for cam ramp and lift that can be achieved there. One reason for rockers to have ratio higher than 1
- Cam ramps comes "faster" so actual time when valve is open is higher with high ratio.
- When ratio is higher than 1, lifters and pushrod move less with same valve lift so softer valvesprings are ok.

There are some reason I come up and there are probaply many more !!

Re: Rollor rocker issue

Hi folks,

I kindly thank you for your replies. It sounds like self-aligning are the way to go. What are my choices for 1.6 ratio self-aligning, using my stock heads, with a possible upgrade to L35s at a later date?

Again, your input is very appreciated.

Hi All,

Just discovered that Harland Sharp makes 1.65 ratio rockers. Anyone know if: 1--they are self-aligning, and 2--will they fit under stock Syclone valve covers?

Thanks in advance.
