That graph is screwy. It didn't make 400ftlbs at less than 1500 rpms either lol.

I have seen them skewed that much with an unlocked converter.

Peak torque looks to be at 4300 rpms.

All torque measurements below 2800 rpms is converter flash.

Also.....this engine should've made power > 6000 rpms. They ended the dyno run a bit early.
