GEAR INFORMATION
The Pro-Billet PN 8451, PN 8452, PN 8455 and PN 8456 Distributors are designed as a direct
replacement for Ford EFI High Output engines and are equipped with a steel gear for the hydraulic
roller camshaft.
The PN 8453 model is a replacement for 351W engines with a TFI Ignition module and is supplied
with an iron gear (non-roller camshaft).
REMOVAL
1. Remove the existing distributor cap without
disconnecting any spark plug wires.
2. With the cap off, turn the engine over until the rotor is
aimed at a fixed point on the engine or firewall. Note
this position by making a mark (Figure 1).
3. Place the distributor cap back on and note which plug
wire the rotor is pointing at. Mark the spark plug wires
and remove the cap.
4. Disconnect the connector from the distributor’s
ignition module.
5. Loosen the distributor hold-down clamp and slide it
out of the way.
6. Lift the distributor out of the engine. Note that the rotor
rotates as you lift it out. This is due to the helical cut
gear and should be taken into consideration when
installing the new distributor.
