I have an old spec book that lists the information on a 1978 440 stock cam. There are a whole lot of specifications so if I miss what you are looking for let me know and I will take another look.
Rocker ratio - 1.50 Valve lift Intake - .434 exhaust - .430 Intake valve timing - opens 20 degrees BTDC, closes 60 degrees ABC, duration 260 degrees. Exhaust valve timing opens 70 degrees BBC, closes 18 degrees ATC duration 268 degrees, overlap is 38 degrees.
Hope this helps.
