Do you have the right flywheel on the motor? I believe the flywheel for the 400 sbc differs from other sbcs. I am grasping at straws, maybe you put the shift kit in wrong, you say it sounds like motor is turning 3500 rpms at 55 mph, sounds like trans is not shifting into drive, that is way too many rpms unless you rear tires are like 15" in height.... LOL. Good luck.
