Mine is still in progress, but we're using manley turbo tuff rods, JE 10.5 pistons, ACL race rod bearings, ARP head and main studs, GSC beehive valvesprings, and OEM gaskets.
I blew my stock block at 470whp. We're mixed between a rod giving out from the stress, or a potential rocker failure. Can't confirm either way at that power but it did lean more towards the rocker, as the other 3 rods didn't look too stressed yet.
The stock rods are definitely a weak point. That's why you see so many supercharger kits eating rods (low end torque hurts them as you assumed). Upgrade them if you want 400+ reliably.
