Iight boys. I just got my stang back from the mechanic shop. I ended up puting a new cylinder head on it. The mechanic put it back together, and I drove it home. Put the mechanic told me that there is a crack in my exaust manifold, and one of my pulleys is bent. That pulleys kind of hard to explain. Anyway, the problem is that it lacks power. I thought for being a small car, and havin a 4 in it, it would push more than this. Any thing anybody can tell me, so that I can get my power back??
