Well I have a decision to make. I can get a remanufactured 302 for my 69 stang for $1050 for a Long-Block. If I was to rebuild my engine myself It would cost at least this much I think. It is a numbers matching car....today. How much of a sin would I be commiting to just put in the remanufactured engine? Should I pay the $175 core charge and keep my old numbers matching engine to sell with the car some day in the future? What do ya think?
