The Ford 427 SOHC: Through The Eyes of Legendary Engine Builder Ed Pink (His LAST Engine Build)
What happens here
Ed Pink explains another significant challenge with using a Ford FE block (the basis for the SOHC) with the SOHC heads: the oil passages. The FE block was designed for pushrod engines with lifters, but SOHC heads eliminate lifters, leaving open oil passages. Ed Pink had to devise a way to plug these passages and create new ones to ensure proper oil delivery to the camshaft bearings. He also discusses the concept of "top oiling" (feeding oil directly to the main bearings) and the issue of maintaining oil pressure. The video then transitions to discuss piston rings, specifically the "Dikes" top ring, an innovation from the 1950s that used gas pressure behind the ring to force it against the cylinder wall, providing a better seal than traditional ring tension.
Goal: Describe the necessary oil system modifications and piston ring technology relevant to optimizing the SOHC engine.
