motor was knocking real bad. a shop told me the rod bearing were going out. they wanted to put a new motor in it. so i checked with u guys and got a bunch of suggestions. i thought the whole time i sounded like a spark knock but everybody kept telling me it sounded like a rod. so i followed u guy advice and it turned out the superchip in the comp. was coming out causing it to run way to much timing and i fixed it today. thanks again. u guys are awsome.
