Go for the lowest gear , 1st  of reverse.
Could always slip a piece of pipe over handle to increase leverage to reach torque required. Would allow a better swing.

not in this case, go tallest but a lower gear would be stronger . it may pay to have someone stomp on the brakes as well.

Any idea if top gear would put more strain on the powertrain than it's designed to take?

I think I'll try this trick with an old belt and 2 pairs of vice grips anyway, just for fun.

  Mick is correct. 1st Gear and 'snipe' the bar with a length of pipe. 

For the benefit of future incredulous readers , especially those who have an auto transmission; removing the starter motor exposes the ring gear which is an ideal place to lock the engine.

How so? Surely being in top gear will provide the greatest resistance and least torque transfer where by low gear will only multiply the torque generated at the crank and output at the wheels making it even harder to hold the vehicle

what do you use to then lock it?

Try any gear   
DEFINITELY use pipe

actually Mick, I think I tried this once on my old galant and I think mother had to get on the brakes for me because even in the tallest gear since I was actually generating whatever torque it was the wheels would creep and there was a bit of spring loaded up in all the drivetrain. On an Astra I managed to jam the ring gear because the access hole was deisgned for that purpose.

and on my last drama, I just went stuff it, rattle gun and loctite

Old mechanics have an "abortion box" full of useful tools that they have made for various jobs. I use an old starter motor cog welded to a bracket. Took mins to make. Hours of fun later.

on the matter of which gear???? on a front wheel drive car, the hand brake only works the rear, so the size of the four wheel chocks are the most important. 

Next episode: ' two high speed vice grips kill dog and swooping magpie.'

Given the unraveling saga, who is going to stamp on the foot brake? I imagine that all of  hb09 's neighbours have retreated to safety and are locked inside their homes with their children.

A Galant !, a blast from the past.
Remember once at the local street drags:
 A Galant , 265 hemi & 4 speed ( yes, there was a remnant of firewall left), stock diff & wheels and brakes of course.
Lost every race race it entered.    Traction ? !  , what's that !    
@nzenigma
Not an A-box, but, bespoke mechanical equipment.

You seem like a creative person. If it's just body weight limiting the torque you can apply, then put on a backpack with water bottles inside, or similar. Use oil as you mentioned, if that reduces the required force by 15%.
 A tap will be much better to chase the f. Thread than a used bolt. Maybe you can borrow one. A bolt can be used, but your should grind verticle stripes down the threads so it resembles a tap.  The f. Thread appeared clean, if you can get another similarly galvanised bolt with the same thread in and out by hand it should be OK.
