360 does not seem to be making power and is slow in the 1/8. Need help and/or suggestions

Yes sir, what would you like to know? I bought the car with good intentions to do something with it. It ended up sitting in my garage for awile without being touched. I ended up selling the car to make room for another car. Then, my oldest son, who started this post, decided he wanted to go racing. I wish he would have told me before I sold it.
