That's quite unusual, the usual cracking place on the 4.2's is between the bores, simply because the bore is much larger on a 4.2. The smaller blocks generally don't crack. I wonder if someone used water instead of antifreeze and the block froze?

I'd be inclined to mention it to the people who sold it to you, though any recompense seems unlikely especially after the long journey. It's nice to have an old 3.4 block for its strength (though you may be questioning that at present), while a larger bore offers more torque. Either way, good luck with the work. You seem to have found a good workshop. It may be worth having them go over the car thoroughly and sort everything before you drive it home.
But the 3.8 has Brivadium sleeves which make it even more tough/robust.

update.

will be having a short block installed that will be rebuilt to my specifications.

i plan on having main bearings, rod bearings, and rings replaced as a minumum. considering new timing chains, tensioners, oil pump too and maybe a balancing of crank, rods, pistons, flywheel, ablative clutch plate and pressure plate too. everything on the heads will remain as is, as well as carburation and accessories.

i will be flying home to california (am now in columbus oh) and fly back when the car is ready. which i expect will be in a couple of months at least.

BTW, the service center doing the work (the rebuilding and any machining will be subcontracted to whomever at the discretion of the service center) is Wendell's in delaware, oh. this was not by design, but by necessity, not that i have any good reason to judge them, or anyone for that matter on the quality of work they do. all that i can say about them as that their garage is large, clean, well organized and that i saw a very nice tr3 in there, an edsel, an old thunderbird in the midst of a body off restoration and a couple of deloreans.

If Jose sent them his engine do you think they would assemble it for him. Jose is struggling to find anyone in the USA to assemble his 3.8 XJ engine from his S Type as it is English and not the same as an American engine.

In the words of many of the Jaguar scribes re the 3.8 S type. I will quote one that sums things up.

quote
"Not many Americans could understand the attraction of a relatively small imported saloon that cost more than all but the most expensive Cadillacs of the time and demanded specialist servicing. By contrast, any half-competent US mechanic could deal with the Cadillac’s 340bhp 7-litre V8 engine – and in those figures lay part of the problem. It was difficult to maintain social prestige against a Cadillac owner with an imported car that had an engine only just over half the size and with a mere 220bhp; Americans had to drive the car to understand its merits."
unquote.
