• Modern roller camshaft, for hydraulic tappets with rollers

• Ignition sequence as with the 351W and 5.0HO: 1-3-7-2-6-5-4-8

• Can be used for 289, 302 and 351W engines when converted to roller hydraulic tappets

• Camshaft made of steel, instead of cast like the original, which is why the pinion on the distributor must also be adapted to steel

• Due to the larger valve overlap, slightly less vacuum is available than with the original camshaft

• Also very suitable for 347 and 408 stroker engines
