Dip stick length

Like he says, but if it's a factory style pan, and you have the magnum tube, get another another magnum stick, like from a van.
Don't cut the factory end off.

Drain your oil, add FOUR quarts. Don't pull the filter.

This is the new 'add oil' level.

Drive the pin out of the handle end, cut off THAT end in small increments and drill a new pin hole when you've got it set to the proper add oil level. (You'll need to factor in how much sticks up into the handle)
Nobody will ever know it's not factory.

Add that last quart. Done.
