72 Demon slanty-to-340 Resto

Stock timing chains were a cheaper made deal, and the tensioner certainly helps keep the timing true. Its a great idea. I am planning on a mild 318 to use in my car, and then transfer eventually into my sons car, i will likely use an aftermarket higher grade single roller , and V6 tensioner in it. My 408 will have a beefier double roller setup.
