My 400 crank was .020 on the mains and .050" on the rods, as I was running 6.8" rods with BBC rod bearings. Survived 10 years of street/strip duty, the last 3 years on a 120 HP plate nitrous system. Ran into the mid-11s on spray at 110+ MPH.
The crank was fine when it came out 10+ years later. No worries about cast crank strength for me.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
