I'm not an expert on the Packard V8 by any means, but I HIGHLY doubt that any parts from a Packard V8 will interchange with any Russian engine. Besides the obvious differences, you also have Metric measurements on the Russian engine, which usually don't translate well to the SAE measurements the Packard was built by. Close only counts in horseshoes and hand grenades. Something could possibly made to fit, but I doubt that it will directly bolt in.
That being said, let me have some time with one of those Russian engines and I'll tell you what will work and what won't, from any American V8.
BTW, the only American gas V8 from the '50s that uses wet liners that I'm aware of is the REO truck V8 that came out in 1954.
