I have had engines built without dyno from shops I trust and no issues beyond easy to fix oil leaks. Dyno plus lots of new parts including stroker kit adds up fast. Shop around for an un-cracked head, rod(s) and skip the dyno and lots cheaper (stock stroke).

Personally, I would wonder why the rod bent? Also is 40 over OK or does it need to go 60? Are cylinder walls thick enough at 60? Agree it may be worth shopping for a better core engine to start with.
