| − | The 396/402 and 427 ci BBC engines were internally balanced. The 454 BBC engine is externally balanced. The 454 can be ID'd by the balancer having the inner hub cast with an integral counterweight. A 454 will also have a different flexplate/flywheel, having an added counterweight that is missing from the other displacement BBC engines. Like the SBC aftermarket dampers, the counterweight of a 454 damper might be bolted to the hub. | + | The 396/402 and 427 ci BBC engines were internally balanced.
