LUGNUTZ Have a book like a peterson publication that helps in identifying that stuff. A friend gave me a 283 block that matched up for my 1960 Corvette,he said it had been an injected one,had a 3735236 shaft that had a factory looking drilled snout. Might have been careful work at home,only drilled one (283) Iv'e seen. His neighbor who is 91 gave me a booklet on how to work on that injection. So better lay off not truck !!
