Description

The ATK ENGINES HP89CBLK is a Chevy 350 Complete Engine with 390HP. It is a universal fitment for Chevy 350 applications that utilize an OE roller block, 4-bolt main, 1-piece seal from 1996-2000. It is important to note the oil pan limitations, as it is not suitable for Chevelles with steering behind the crossmember, some Corvettes, and 1962-1967 Chevy II's.
