Desperately need experienced opinions on Engine Identification

Did you ever get that car running I have 2 ) 273 engines 65 barracuda all new rebuild putting together bored 30 over And one 65 dart Was running When wrecked 65000 miles Both have 904 transition trunnion joint


My car is a 67. The only way I would install a 273 is if it was a matching year. Thanks anyway. I bought a complete LA 318 crate engine for the same price as an Eggers parts kit for the 273.
