1.6 Rocker Arms for /6

The welding did seem a little more difficult than mild steel. The nice part is you can weld 360 degrees around the cut and maintain its strength. TIG welding would work nice here. As you can see, not much heat is put into the arm. I used a standard cut off wheel. .070" I believe. It moved the ratio to around 1.58:1. Stock push rods would work but only marginally. I had to run the adjuster in quite a ways for the distance change. To do it right, new push rods would be in order.
