I completly sealed the engine before I put it in I dont know what the issue would be maybe I did something wrong when I ported and polished it...... Oh well I think I want to put the lrp in it its just weird how the 28's have more power then the 36 that comes in it. Just about everyone I know said that the 5.9 is garbage and that they never do wheelies but mine does wheelies on command lol tons of low end power
