A beautifully machined solid billet timing cover is a direct replacement for 96-97 LT1 cars.  The integrated crank trigger boss and larger distributor housing bore allows you to run a late style Opti-Spark ignition on a 92-94 LT1 without the hassle of trying to obtain the hard-to-find factory cover.  This cover also has more internal room to run a double roller timing chain set.  This cover is offered as an optional piece with EFI Connections LS conversion kit.  Machined in house from 6061 alloy, anodized Black for a look that will not pit or corrode.
