Stock crank appears plenty stout, best not to introduce variance where it is proven not to be needed.

For the lower spec blocks, I asked about what rods they are using and their reply was "IAG spec H Beam" so I am assuming Manley or something similar. If you go up in " stages" they use name brand rods.
I didn't really look mine over comparatively to see what they did to improve oiling, if they actually did anything. The car runs great and is definitely less noisy than my previous few stock blocks, but I am attributing that to properly shimmed valves and careful assembly.
