Advancing the timing...
Wow, guys I have owned my 92 F-150 with the 302EFI going on 5 years now and never even looked at the timing and today for some reason I said what the hell and made a discovery that my timing was set for some reason to 0 TDC, so I set the timing to 13* TDC and what a difference I could feel as far as the seat of your pants difference. Now even with my 33 inch mud tires that I have on my truck and I can bark the tires like there is no tommorow. How much HP and Torque is gained from advancing the timing. Just to make sure I took the truck out for a spin and put the motor under load and it didn't ping so I think I found the sweet spot the first time. Just thought I would share this with you all. It feels like I picked up a realistic 20hp to the wheels, that's crazy!

Okay Wheel
Step 1 - Disconnect the negative side of the battery
Step 2 - Unplug the spout connector over by the TFI module
Step 3 - Get under the truck and clean off the balancer so that you can see the marks as far as TDC, 10-20 etc... You will also want to mark the TDC 10* also and mark the pointer so that it will be easily seen when using the timing light.
Step 4 - Grab your handy timing light and hook it up
Step 5 - Start the truck up and point the timing light to where those marks were on the balancer, I marked the balancer with a blue permanent sharpie so it would be easy to see, you can also use chalk to.
Step 6 - If the truck is already timed at 10*, try advancing the timing 2* until it pings then back off a 1*. To do this you need to loosen the distributor hold down bolt and turn the distributor clockwise a little bit at a time, then you need to start the truck up and see where the timing is like step 5. If the timing is where you think it should be plug the spout connector back in and take the truck for a spin around the block, but be sure to put the engine under a load that is when you know it should ping if anything.
