Mine were solid in my Z. Crank-not so much. That said I would never put stock Z or stock LMM pistons back in an engine.

Mine too. As much as 700hp on mine, but yes I know them or the crank could go at any time.

I have to say I'm pretty dang satisfied with the Ultra Billets, Howards rods, and Fingers setups. Especially after initialing a 1380 Spicer slip yoke, and then chewing the teeth clean off a seized CP3 pump. Plus on first hard dyno pull, the brake valve slammed shut and brought that same engine to a pretty instant stop.. Spinning 6k lightly loaded, I seriously never even think about the weak bottom end pieces now. If the theory that piston cracks start at the wrist pin is correct, then my pins must be pretty happy with the pressurized pin oiling addition. Pans coming off next week, so we shall get a better look for 100hrs of beating.
