I don't know how much you know about the subject so I will start at the beginning. First you have to get to it, you can pull the motor or leave it in the vehicle. Its a little harder with it in depending on the space you have in engine compartment. If your leaving the motor in, which I imagine you are, your going to have to take the front end of the vehicle apart. Remove the grill, bumper if need be, radiator, fan, water pump, harmonic balancer, you will need to buy a puller and a installer for the harmonic balancer. You can get a puller kit from harbor frieght tools for $10. You can buy the installer from summit raceing (web site) for arround $30 or you can buy one that will do both the install and removal from summit for $70. Once you have removed your harmonic balancer you can remove your timing cover to expose your timing chain. Turn the motor using a socket wrench until the timing marks on the crank gear and cam gear line up. The marks are usually just white dots, you want the crank mark to be up towards the cam and the cam mark towards the crank, the marks will be up and down from each other. Once you have the marks lined up remove the bolts holding the timing chain to the cam and crank. Remove the timing chain as a whole unit with the cam and crank gear still on it. If the crank gear doesnt want to come loose use your puller on it. when you get it off just put your new gear on and line up the timing marks then put it back on as one unit. If you cant get the crank gear on all the way by hand buy a crank install tool (summit) they run about $24. While you have the thing apart it would be a good Idea to put a new timing chain on. Depending on your vehicle this would also be a good time to change your cam if need be. Its not that hard to do it just takes a while, take your time and don't force anything.

It is in the passenger side of the timing cover towards the bottom.

Line crank shaft pulley timing mark on tc mark on timing belt cover. Look at cam shaft timing belt sprocket and locate the small triangle (not diamond shape) located on the plate attached to the timing sprocket. Referencing the timing sprocket look approximately at 5:00 o'clock under the timing sprocket and locate the other small triangle. Line these 2 marks up. Put timing belt on. Make sure the cam shaft sprocket and crank shaft sprocket do not turn while installing the belt. The crank shaft pulley must be removed in order to get the timing belt on.
400 has a longer stroke
install 3.8 Chevy impala crank sensor passenger side , remove wheel and use pully to pull out crank shaft
Chevy did not use a crank sensor on that year.
There are two timing marks on a 350 chev one for the cam shaft gear and one for the crank gear. The timing mark on the crank or the on on the bottom of the motor should be facing straight up and the cam shaft gear should be facing straight down this will put you lined up and top dead center.
Check the crank shaft pulley
It's behind the timing belt cover on top of the crank pulley.
That year model does not have a crank sensor.
It is on the front of the crank shaft and under the timing belt cover. You have to remove the crank pulley and all the belts and then the lower timing cover. It is not a job for a beginner.from : http://repairpal.com/crankshaft-sensor-569
