'70 Duster - First MOPAR Build

this was a 6 cyl at birth now 408 stroker
Awesome. Do you mind me asking if you built the 408 or went with a crate? 2 years ago I swapped my '70 Firebird from the original 350 to a 455. I sourced the parts and built it myself and it came in about $2000 over the cost of a crate motor. So, now I'm torn on how to proceed with the 408. I hate leaving the fate of the engine in the hands of someone I don't know, but saving some money is never bad.
Thanks
