Trans is an E4OD and will bolt to the small block V8 pattern. This trans requires computer control to function correctly. The computer is calibrated to the truck in factory trim. To make this trans work as designed may require a stand alone trans controller, esp. if you are going to use a carburetor.
Exact engine info is REQUIRED for a comprehensive answer to your query. Right now all any of us know is that physical mating can be acheived. Operation of the trans remains in doubt.
