Does anyone know the stock 260 cam duration? Also is the lift .433?

Sure, stock duration for the 260 is 252 degrees. And no, stock lift is not .433", it is .410"(.276" lobe lift times 1.5 rocker ratio). Only the later ZX cams were .433" valve lift(.288 lobe lift times 1.5 rocker ratio).

I appreciate it, boss.
