What are ways to remove the 1 1/2 inch nut at the front of the crankshaft on a 232 engine?
I have bent the retaining clips out of the way.

The job I will be doing is replacing the front oil seal.
The engine is in the car. I have taken the radiator out.

Use a socket spanner, and hit the bar with a large hammer to shock the bolt loose. Or you can remove the flywheel cover and wedge the ring gear to stop the crank from turning.

The easy way is to put a socket on the crankshaft nut & hit the starter button so the end of the bar hits the chassis frame or something solid . Better make sure the ignition is disabled or you could have spanners flying everywhere!

If it is like every other crankshaft nut, use a impact driver and a impact 6 point socket. (even if you have to rent)
sometimes you can strip the ring gear or mess up the starter. 2 cents

The nut shouldn't be that tight that the starter will even notice anything. The inertia of the flywheel should be enough to crack it. The issue is not that the nut is tight - rather that you are not pushing against something solid.
As always, I'm only stating what I would do, not telling anybody else what they should do. There are often a number of 'right' ways to do a job 😉

Hugo, I decided to use your method. I put a 1.5 inch socket on the nut, with a breaker bar. Both are 3/4 inch drive. I noticed that the bar is long enough so it would would hit the frame when it would swing. I positioned it so the bar was hanging between the battery and the radiator support. It took only one try of the starter to loosen the nut!

Thanks to everyone for your suggestions.
