Description

454 HO Partial Engine(short block) Used as the basis for GM's 454/425hp and 454/440hp Crate engines.

Notes:This engine is configured for a mechanical fuel pump. Fuel pump pushrod is not included. The timing cover that comes with this engine will only accommodate a late model single roller timing chain. If a old style double roller timing chain is used, a Gen V sheetmetal timing cover must be used .If this timing cover is used, only half of the bolt holes are drilled and tapped in the block (this is how the Gen VI timing cover is set up) The extra bolt holes will need to be located by using the Gen V timing cover as a template and drilling and tapping the holes accordingly. This block will accommodate a factory Gen VI roller camshaft or an old style MarkIV flat tappet camshaft. This engine is drilled and tapped for a mechanical "Z" bar clutch linkage ball stud. Accessory Bolt holes in front of block are in the same standard locations as the old Mark IV block, but are drilled and tapped for 7/16-14 threads instead of 3/8-16" some mounting holes on accessories may need to be modified. This engine comes equipped with a 14" Automatic flexplate. If using a 4L80E transmission, only three torque converter bolts will line up. This engine comes equipped with a 6 quart truck style oil pan. This pan will not fit Chevelle, Camaro, Nova, Impala. It will however fit most 2and 4WD pickup trucks and 63'-82' Corvettes without power steering.
