You could get anything from the 225 "Slant Six," 273 V-8, 318 "wide block," 361, 383, 426-S, and the 426 Race Hemi. If you can find the data plate under the hood (probably on the driver's side fenderwell) and post the codes, I can tell you everything about your car.
If you include which model Coronet and the bodystyle, that would help since it can narrow down the engine choices.
