"Baby my muscle cars"...uh...no. That doesn't sound like me. I don't baby any of my cars. I drive them hard and maintain them well.
Not to argue, but it sounds like you listened to one guy, which isn't "listening to people with credible experience". Listening to "people" would mean more than one guy.
I'm not saying cracking doesn't occur, it does. If he has an engine that puts out enough poop to cause that kind of side deflection on the gears, then yes, an M22 can crack. But the good news is, stronger than OEM cases are now available, so all he had to do was buy an improved, re-engineered case and rebuild one of his M22's and he'd still be racing on it today.
The reason I'm sure my M21 is still alive is because I'm not running slicks and I'm not drag racing it. That puts a LOT of additional stress on any transmission.
You have now officially heard from someone else that has "credible" experience.
