ok i finished the swap like two months ago but i want to get it running good and when you drive it and rev high it will rev fine until like 3 grand, when is hit that it like gets no power then when it gets to 4 it revs fine again....or when im driving and floor it it will go fast to 3 grand, get no power then when it hit 4 it will take off again......you can hear the engine get louder when it hits 3 but it just gets no power......does anyone kno what it could be......i really want to get it running good before i get it on the road..........thanks
