Generally, if you have a quality socket and a long breaker bar with a cheater pipe on it - it will come loose. You do need a method to hold the engine from turning while applying force to the breaker bar. The best way to hold the engine is to remove the starter and attach a flywheel holding tool into the flywheel. If you have a helper, the helper can wedge a large, flat blade, screw driver into the flywheel teeth and hold it that way. Both will work. There are other ways and I'm sure you'll get more comments on those. An impact wrench is not recommended because the hammering can damage the delicate crank bearings.
The tool in the picture is about $30.00 on ebay.

if the car is a manual you can put it in 4th gear, pull the ebrake tight, and chock the front side of the tires... that should keep it from moving enough and you can get a breaker bar on it from the top, a cheater bar on the breaker bar helps... just be careful so you don't slam the breaker bar into the car when it breaks free

IF you are replacing the balancer..
You can heat up the bolt with a propane torch..
You don't need to melt anything down, but the heat help to release
the factory threadlocker on the bolt. Then you can just hit it with an impact
gun.. Remember the OE bolt is a 1 time use only. Go with ARP when replacing

I have removed several on stick cars. Emergency brake, rear wheels on the ground and a high gear (5th). I just used my 1/2" breaker bar and a good socket.
I would not attempt with bumping the starter. The starters on these cars are bolted to an aluminum casting and many have had the starters break off for other reasons, IMO using it to try and remove the crank bolt is asking for big problems.
