My Engine Dilemma..need honest answers

[SilverMachine]

Ok, so after letting the engine break in for awhile we were able to put the initial timing at 8 degrees, it was at 0 before. it feels like a completely different truck now! My mechanic said we will try to get it around 12 degrees initial timing during my next oil change. so the initial timing at 0 was the problem! hopefully it will be even better at 12 degrees initial!
