New ATP Graywerks timing cover.  This is a cover with timing tab, and is a stock replacement cover for factory Tuned Port Injection (TPI) engines (the timing tab is different location vs other SBC engines).  This ONLY works with a factory GM balancer!  This does not include any gaskets nor mounting hardware.  Cover is bare (unpainted) steel.   Fits the following:

85-92 303/350 5.7L V8 Camaro
85-92 305/350 5.7L V8 Firebird/Trans Am
85-91 TPI Corvette

NOTE : This cover is specific to the TPI engine, which has the tab at roughly 2:00.  The 88-92 TBI engines and 1987 and older carbureted engines have the tab in the center of the cover instead.
