67 Cuda 273 replacement options

Well just a couple options here would be a 360 crate motor, carbed or EFI. The other option would be a 318 or 360 Magnum motor and the stock EFI. You'll get a complete running engine and the EFI option makes it very driveable. I'd love to build a 273 but honestly bang for the buck and driveability in your price range would tend to lean me towards a Magnum 318 or 360 with stock EFI.
