Just asked my machine shop (that has quite a good reputation) this very
question, and they said that the cost to balance is significant and in a low
power, low revving engine like the 2.25, I would be better off spending my
money elswhere.
So I am...and am...and am...

"But seriously. Is it a good idea to get the crank and con rods balanced
for
a 1970 2.25petrol lump when doing a rebuild?"
Depends...if you need to get the crank magnefluxed for cracks and the
journals machined anyway, why not have the machinist/shop balance it too,
cost is just a few more dollars, and while he's at it, why not "lighten" it
up a bit and knife edge the counter-weights as well?...only a few 'more'
dollars and the benefits are quite obvious, even in a tractor engine like
the LR 2.25 and you will not ever have a better opportunity for these modest
but beneficial improvements.
...but if you are doing your own journal inspection and deem them
acceptable, then just simply replace the bearings...no need to take it to
the machinist's shop and spend any dollars.
