Hemi engine swap..is it worth it

Well I took the Hemi to machine shop today for a tear down and to have block and heads checked for cracks and see if all is well. Guy I got it from was sketchy lol. He said is a 2014 engine are there number I can look at to find out. It has eagle heads for sure but that doesn't mean someone didn't swap them onto an older engine. It has the mds as well. Is it easy to delete the mds.. If all turns out well just going to buy rebuild kit for it. Any recommendations on where to get one..a good one. Thanks just looking to do a cam swap to up the power some. What hp could I expect with a cam..will be a street strip car 3.55 gear in my Dart. Fingers are crossed all checks out ok. Thanks guys
Well engine masters got 500hp with a cam swap using the holley efi.
