“The Corvette got a 350 version (L98) and the Camaro got a 305 version (LB9) available in the Z28 or IROC-Z. LB9 was available with automatic only. L69 H.O. 305 was only available in the IROC and only with 5 speed manual. L69 production was restricted half-way (April 26, 1985) through the model year.”
You don’t need to be disturbed anymore.
