blown engine?
 

I would like to get your guys opinion.Well heres the problem went to the track ran 3 passes the first 2 passes the car strong and I got my best times ever in this car the 3rd pass got half way the track got it into fourth gear and noticed it wasnt pulling as hard.I stopped to pick my time slip up and the car died I tryed restarting it and the engine didnt want to turn I thought it was seized up.So we pushed it and got it started it that way.so now the car wont idle and sounds like a bunch of nuts and bolts in a can rattling around very loudly and it sounds like its coming from the driverside side of the engine.I still have normal oil pressure no check engine light and no smoke.what do you guys think the engine is shot?

something might have given loose in your drivetrain...but its hard to say, can you localize it any more? If its pretty bad I wouldn't run it any longer than just to determine where the sound is comin from...then prolly take off the top end if you think its coming from that end

Take off the driverside valve cover and check for loose pushrods. Is it a taping sound or more of a knocking sound?

It sounds like something came apart and its not a ticking or knocking. it's a real loud rattling sound like nuts and bolts in a tin can. I will pull the valve cover off and take a look.

Prob broke some valve springs or a rocker came loose and off the stud. If everything looks normal under the VC's then pull the intake to check the lifer valley to make sure your spider clamp is intact and not bent as this can cause a lifter walk out if you have bent any of your valve train (ie pushrods, loose rocker, etc..) Lastly, drain your oil and look for metal on your magnet (if you have one) or for particulates in the oil - sign of spun bering. Good luck.

Check inside the bell housing for unsecured material.

I pulled the oil drain plug and it was full of metal. Time for a rebuild

Yup, that sucks. Go the 355 or 383 route now. Perfect time ;)
