Good catch — the cam in the photo is a Isky (Iskenderian) unit marked FL-358 (as seen: “FL-358” on the face). Based on the catalogue data, here are the key specs for the FL-358:

  • Application/Range: ~ 2,500–6,500 RPM iskycams.com[2]
  • Valve lift (intake/exhaust): 0.512″ intake / 0.512″ exhaust (solid lifter version) iskycams.com[3]
  • Duration at 0.050″ lift (intake/exhaust): 244° intake / 244° exhaust iskycams.com[4]
  • Advertised duration (intake/exhaust): 278° / 278° iskycams.com[5]
  • Lobe separation (centerline): 108° CarID Images[6]
  • Rocker ratio assumed: 1.6:1 (for this series) iskycams.com[7]

If you like, I can pull up the full valve-train recommendations (springs, lash, pushrods etc.) for this cam to match your build.
