Then I guess I don't know. Usually, $150 engines from old bread trucks aren't 377's, but I suppose stranger things have been built.
BTW, what's the rod journal diameter? You could have an offset ground LJ crank fitted w/SJ rods, can get a 3.5625" or 3.625" stroke that way. We used to call these engines "9/16" and "5/8" engines, respectively.
More displacement can be had from a LJ crank if it's based on the 1.88" Honda rod journal size.
All I see on the piston p/n shows a rebuilder-type (1.540" pin height) 350 piston.
