Do not take any more than about 60 thou off the rocker.
NOTE: I typically polish the underside of a cut rocker to help mitigate stress risers in the metal. Shot peening is also necessary of ya have big spring pressure IMHO. NEXT: I helped a guy last year with GEO. It was an unknown combination to me. It took 60 thou + under the rocker stands to make the GEO work. This engine is still running in his race buggy. No problems and he has a full season PLUS on this engine (So Far) And he has around 200 pony's to have fun with. In truth. I don't know what the max is. Me thinks you will have to shim until you get it right. PERIOD. Irrelevant of the shim thickness. Thats my .02 worth. And THANKS for chipping in Craig and Len. I learn something every time one of these threads come up. Clayton |
