Product Details
The 454HO engine is a fully assembled long block that also includes the intake manifold and water pump. This engine is assembled using brand new, premium quality components. The 454HO engine is manufactured on current production tooling; consequently you may encounter dissimilarities between the 454HO engine assembly and previous versions of the big block V8. In general, items such as motor mounts, accessory drives, exhaust manifolds, etc. can be transferred to a 454HO engine when installed in a vehicle originally equipped with a big block V8 engine. However, as noted in the following sections, there may be significant differences in the water pump, torsional damper, etc., between a 454HO engine and an older big block V8 engine. These differences may require modifications or additional components not included with the 454HO engine. When installing the 454HO engine in a vehicle not originally equipped with a big block V8, it may be necessary to adapt or fabricate various components for the cooling, fuel, electrical, and exhaust systems. Due to the wide variety of vehicles in which a 454HO engine can be installed
