It will require a couple hundred dollars in special tools, for most people having someone else do it is a better deal.

 

Do a search, some guys have talked about marking the harmonic balancer and moving the timing about 1/4 to 3/16. When I changed mine the first time it was at about 12 and we moved it to 18.5 it was a bit over 3/16. A buddy of mine has the gauges to set timing, I was afraid to try the mark moving deal. Timing sure does make them run better.
