It shows the engine as being externally balanced, which probably means it should use a 400SB (externally balanced) flywheel.....but I would sure check with the tech line to be sure. If it doesn't come with a balancer it will also need the corresponding externally balanced balancer.

Then you need to decide what size flywheel you need (153 or 168 tooth) which will be dictated by the bell housing you're using.
