Does anyone know any of the engine block casting numbers and date codes for the 289 hi-po engines used in the Mangusta. At some point in time someone replaced my 289 hi-po with a 1972 Mustang engine. I would like to build the correct 289 hi-po engine for my car. However, I need to know what block casting number and date code I need to be on the look out for.
Thanks
