about a month ago i went out to do some street racing. me and a friend in a stang running consistent 12.7's@102 on slicks and skinny's decided to run em. anyway we line up and he takes me hard off the line, puts like three cars on me right off the bat. my car just spun till 2nd then i started to pull real hard, all of a sudden after 5700rpm it just fell on its face. when i stopped to turn around my car just turned off. it wouldnt idle on its own, and i felt a loss of power all throughout the power band. im thinking spun bearings but i drained th oil and nothing out of the ordinary not even shavings. my oil pressure is normal at idle in park, but when im driving it drops to zero until i take off and it goes back up to 40-50psi. another thing is that my rockers on the pass. side are loose and my timing chain had a lot of play in it last time i checked it. could the chain jumping a tooth cause this? what do you guys think, i've had it parked for a little more than a month now and it just kills me to see it parked

 

If the timing chain jumped it could cause it to not idle, run rough, and not have power. It shouldn't have loosened the rocker arms. Have you installed aftermarket arms and maybe not got them tight? You might check the timing and make sure it didn't jump.
