Advancing Cam Timing - How do you do it!?
So, after PM'ing a member, I've decided to try and advance my Cam timing on my 94' 5.0L. Having never done this before I'm guessing it goes something like this:
- Retard Ignition Timing by 8 degrees to compensate for advanced cam timing
- Bring engine up to #1 TDC
- Remove Timing set
- Install cam gear
- rotate crank until it matches the 4 degree advance keyway on the crank sprocket
- re-install timing set
- re-assemble as normal
- re-check/adjust ignition timing

Whatever Works:
Do your thing as described, then put a degree wheel on the crank and a runout guage on no. 1 intake valve stem and see what comes up. Most timing measurements are made at a valve lift of 0.050".
