In that range would it not be better to just take a core to a machine shop who will custom build an engine rather than a ‘crate’ motor turned out at a high volume engine shop? I’m planning to do a 289 to 331 stroker custom build 😜 I don’t trust the crate engines plus my 289 is original (outside of my car running a 302 now) and has my VIN on it. Even here with sky high prices 5-7 should cover it. But like many items engines and the requisite heads and parts are in short supply.
