Reply to "engine cam bearing oil restrictor install,yes or no"

I did the same as Ital Ford and MkIV...

Lifter Bore Bushings and the Cam Restrictor Bearings (groove on the backside, and clocked to 4:00).

We (4280/MkIv, mostly) also did numerous other oiling upgrades, including:

  • Ported Oil Pump / Block / Filter Feeds
  • Higher Pressure Spring
  • Drilled Squirter Hole for Distributer Gear in Gallery Plug
  • Thrust Bearing Oil Feed Hole (#3 Bearing Face)

    I have about 1500 miles on mine, great cold & hot oil pressure.

    Give me a couple years to report, as well.
