289 High Performance V8 Wider Bearing Caps
|
Wider main bearing caps make a 289 Hi-Po block the real thing. While the footprint is the same as a regular 289 main cap, they have wide shoulders to provide improved journal support at high rpm. Look for the red paint blotch on Hi-Po parts. These wider main caps are also common to all Mexican block 289s and 302s. They are numerically identified differently on Mexican block engines.
