Just Venting, AARRGH...

I've done motor/tranny together with headers in the car. I just tied the headers aside. However, I did not have an aftermarket deep oil pan. I had the front of the car on ramps, and the engine/tranny have to start out almost vertical. Also, I have always done it with the hood on the car. I just installed a 360/904 together into a duster with the hood on, no problems. No headers either.... lol
