Again LA blocks had factory roller lifters from the late 80's to 91/92.
No retrofit kit needed. All I needed was the hyd. roller cam itself. The block already had roller lifters from the factory.
Here is what I used:
Voodoo Retro-Fit Hydraulic Roller Cam - Chrysler 273-360 270/279 (No lifter kit needed)
But now I want this:
Voodoo Retro-Fit Hydraulic Roller Cam - Chrysler 273-360 282/290
Or maybe:
Hughes Engines
