2G Engine caught on fire, what happened?

[NASTYDSM]

Ok, I just sold my 98 Trans Am and my twin turbo stealth and got a highly tuned gst. I bought the car which was tuned and put together by Pacific Performance (who is the best because they hold the record for the pro front wheel drive class ) . Approximately 20 minutes after i got the car it started smoking slightly from the exaust. 10 minutes later I was driving at 60 mph on the freeway and the engine all of a sudden pours out tons of smoke and i pull over. I get out and lift the hood only to see that it is on fire. After 3 minutes, I put the fire out with a large cup of water. There was oil all over the engine bay. Also there was oil in the radiator fluid (very bad sign). I am suspecting a blown head gasket but i am not sure. Just for the record i did run first and second gear out once or twice but that is not supposed to make the engine catch on fire. Oh and it did NOT start to smoke immediately after i ran it out. WHAT HAPPENED? ANY IDEAS?

Was your dipstick in? Yea. That might have been the problem. It will spew oil out onto your exhaust manifold. Oil + Manifold = Fire.

Sounds like your shop is 'the best' at ####ing up your car.

As previously stated....there was OIL in the radiator fluid! A dipstick blowout does not cause this to happen. Also, it has been 2 years since the shop put the car together. I bought the car with everything done to it.
