The easiest way to do it would be to take off your valve cover then pull the plug on the transmission right by the engine code. Then jack the drivers side up and rotate the crank pulley until the TDC mark on the flywheel is at the correct spot, then check the cam gears are also lined up. Its easier to line up the flywheel since its a larger diameter so you have less chance of being off.
Also, there is a dot on the edge of the lower timing gear that points to an arrow on the block for TDC. I've always used the flywheel method though.
