Holroyd BBC Rocker Arms

[QUOTE=james schaechter;253389]Mark, there were some guys welding up the pushrod sides of their rockers and no one in tech had issues with that. The rocker had to stand a lot of heat in that process. The problem seemed to be that if the rocker got too brittle, it would break anyway.

Jim, I was just wondering when it became legal to weld or customize stock rockers??
When we went to Indy in '04 with the 350 Buick, I had already split a couple of rockers at the shaft hole. I wonder how long we would have lasted in teardown if I had welded a bridge piece across the top of my rockers to strengthen them up?

Let's do a poll:

5 seconds

10 seconds

15 seconds
