hi guys, my uncle and i just adjusted the timing on my stock 5.0 grand merc..... is it set back from the factory or was mine retarted (literally) we advanced the timing then tuned it back a lil till it had no more knocks and holy hell does it pull like a bat out of hell, i can linelock all day if i wanted to, one wheel of course unless i varied from forword to reverse, lol but is the timing from the factory set to be retarted that far???
