(im guessing they just flattened the tops.)
well in 01 the compression went up to 10:1 (maybe 10.5:1) and the rod change was probably to save money or weight. Yes the 99/00 is a good year to boost, in fact its what I have and I have boosted it. Their website isnt BS since they did drop the compression and went back to the older style rods, thats how they can get away with saying that.
