Ok I think that I'm ready to advance the timing on my 89 F150 300 I6 (4.9). I've been reading a few things on here about it but its mostly been on V8's. Should I go to 16*btdc or is it different on a 6 cylinder? Are there any threads that walk you through it on a 6 cylinder?

 

its the same...go for 16 and if it doesnt ping its good...if it does go to 14deg...

 

Do i need to upgrade my coil, plug wires, and gap my plugs before I do the timing? Or can I do the timing and then upgrade the other things later?

 

you can bump it without....I did..

I still havent put a brass cap and rotor on or a higher output coil...but I did put an MSD box on and the cap is showing it...
