Who runs a NA Crank???

[Just a Six??]

I think every stock crank ive seen that was broke was between the 5 and 6 rod journal. Makes sense since this area has the least amount of mass and has to transfer the loading of cylinders 1-5 through it under positive load.

Cryro the NA crank & under 500 HP shouldnt be a problem if you dont detonate the crap outta it. Even then, with lots of detonation the HG will probably go long before the crank ever will. Of course this is JMO.

The $ spent on the cryo process isnt a worthwhile expense on a stock crank with the availability decent pricing of stronger cranks these days.
