Assuming this engine is going into a Cobra replica, the same principal probably applies to the flywheel/bellhousing as to the transmission and clutch - it's a light enough car that stress on the parts typically should be nothing compared to putting it in a 4000 lb Galaxie or 3500 lb Fairlane. So a stock bellhousing should never be a problem in most drving. But, if you plan to do a lot of Banzai driving and frequent the dragstrip, there is a lot of peace of mind with a Lakewood or Quiicktime bellhousing. Clutch explosions with stock bellhousings are truly nasty things and can mess your feet or lower legs up if not worse. I used a medium weight aluminum flywheel on my 4.25 in stroke 428 motor and I'm amazed how responsive and fast it revs. Made me a fan of lighter flywheels, but not necessarily the lightest flywheel you can find.
