need your guys help..possibly a hole in my block... Options

[Antz5SFE]

last night i was in 3rd gear in between 4 & 4.5k rpms & shifted to 4th but started to come to a yellow light so i quickly braked & downshifted to 3rd again right away never even hit the gas in 4th & was off of the gas completely at this point. the rpms kept rising even as i came to a stop & i put the clutch in & threw it in neutral as soon as i saw the rpm's climbing. they stayed at around 6k until i shut the car off maybe a second later...& all the oil spilled out of the block. i wont know for sure what exactly is wrong until i get the car up in the air but it seems like there's a hole in the block. i'm trying to gather my options....the best thing to do would be to either do a full swap or get something else? i was not redlining in any gear neither have i ever bounced off the rev limiter in this car. it's a 95 GT w/ a gt-four front conversion. 90k original miles. oil was always changed religiously.

Until you can check the block, you might check the throttle cable and throttle body, make sure both move freely. There has to be some reason the engine revved up the way it did.

As tigawoods said a possible issuewith the oil system. The oil pump eats an enormous amount of energy, if it suddenly had nothing to grab but air I could see the rpms rising. Maybe a few hundred rpm though not to 6000.

The most logical guess I can figure is that either you cracked the head which allowed air into the intake ports or some shrapnel/projectiles from your block caused a massive vacuum leak into your intake manifold. The computer can't recognize the difference between a massive vacuum leak and WOT(the TPS isn't that integral), so with a leak it just dumps the appropriate amount of fuel into the engine and the motor revs out of control.
