Does anyone make a 1.6 ratio rocker for LS1?

The only company I can think of that might would be Jesel. Maybe T&D.

Jesel and T&D both do. Jesel even makes one for the C5R head.
I actually wouldn't mind this, it would play less hell with the PR's if the lifters don't run out of oiling because of the lift. I guess the new Crane lifters can take .400+ at the lobe and they are still safe so that's .640" lift on a 1.6:1 Rocker.

BTW Kurt those new Daytona Prototype LS rules really suck. No Porting the LS6 castings and now 5.0L, the LS is a monster compared to the other motors in there, but looks like the Lexus is finally competiting with it.... I like how the Porsche motor says 3.9L and any modifications in comparison.

On the other hand the drawbacks come from the fact that the rocker will mulitply the loads from the valve spring back thru the pushrod. The higher loads will deflect the pushrod, rocker stud more and put more pressure on the lifters which will destroy stock Hyd Roller lifters faster or wear out needle bearings on solid rollers faster with the higher valve spring pressures.
There are advantages and drawbacks to both. I can go into that if ya want but I'm hungry, so if ya want ask I'll see what I can do.
