Can you stroke a 5.2 / 5.9 , and keep it EFI ????

Kinda redneck, but: I'd bet that if you use a stock 5.9 ECM, you'd be right in the ballpark on a 408 (.030" over block with 4" crank) if you bumped fuel pressure 10%.

5.9 computer would run a warmed up 5.2 but you would still need some computer upgrades, 5.9 would definatly need it
