Roller Rockers in Stock Elim?

I may have a option.

Many years ago, a friend and myself were searching for a way to minimize breakage in manual transmissions and differentials. We sent quite a few gears out to have them frozen. This cryogenic process is suppose to 'relieve the stress' of the parts.
Can't say if it really helped, but it certainly didn't hurt. I would say on an average, any frozen gear lasted at least as long-if not longer-than the unfrozen gears.

Some months ago, I spoke with Mike Long of G-Force and asked his opinion on freezing the gears in his transmissions. He said they tried it and didn't really see any advantage in the process. However, he said the cryogenics did seem to show improved durability in reciprocating parts.

I had the same conversation with a friend who builds engines for late model circle track cars and he explained he had every connecting rod frozen in every engine he builds.

I bought a set of Crane Nitro Carb rockers some 10 years ago and had them frozen with those transmission parts. Last month I broke the first one of those rockers. It broke about the 1000ft mark. I shut the motor off. Had the car pulled to the trailor, replaced the rocker, got back in line. Red light in the final...Yes, that was luck. Or was it? I'd say they had 400 runs on them.

Maybe the cryogenics help. Maybe you just have to put X-amount of runs on them and throw them in the trash. I may run unfrozen transmissions but I will never run rockers that are not frozen!
