To make a long story short, the WOT switch malfunctioned and the fuel solenoid starting dumping tons of fuel into the motor. Black smoke started coming out the tail pipes and I parked it in the driveway and was gonna have it towed to Kustom Motorsports (my buddies shop) in the morning. Well I decided to move it from the driveway to the street, fired it it up and BOOOM! Blew the upper plenum right off the lower manifold. Lower is completely fine and so is the intake tube... luckily there was no nitrous bottle in the car so nitrous wasn't being dumped into the motor just fuel.
