I am planning to start my 460 for the first time tomorow (1/1/02), but I can't figure out what the hole at the back of the engine block goes to. The hole is just behind the intake manifold, in the center of the block. I think that it goes into the lifter valley, but I want to be sure before I plug it and cause problems.
Please help, I HAVE to start the car tomorow, sitting in it and making VROOM VROOM noises aren't good enough any more

.
Thanks,
Bran
