Roller Rockers in Stock Elim? - Page 2

I run a '71 429SCJ Mustang in D/SA like Vic Guilmino and I have also had a lot of rocker arm breakage in the past. Every couple of passes I would break a rocker, usually an intake (the 429 has a 2.25" intake valve which is pretty heavy). I also had a lot of cases where the "sled" fulcrum would split in two. A couple of years ago I bought a brand new set of rockers and fulcrums and had them cryo treated. I have not broken a single one of them (knock on wood). I don't race nearly as much as Vic, and he is making a lot more power than me so his cam may be a lot more agressive than mine. But I did find that the cryo treated rockers seem to be a lot more durable on my setup.

From my experience and knowledge people like Woodro Joosey and Jim Waibel have been pushing for roller rockers for years and if icons in the sport can not get it accomplished, what make any of us think that we are any different ? We run stock for a reason, if we start making drastic changes like this we are eventually going to end up with no stock division at all and we will all be running super stock. With the rules the way they are racers must make the decision if they are to run stock or super stock, not try to race stock cause they think it is easier and try to change the rules to fit what they need, if you have to do that are you truly racing or are you being lazy?
