Don't know the brand timing chain. Supposedly stock but it was a double roller. Don't know when a double roller was ever stock. I have a degree wheel. I don't need to know the exact degree. It's probably going to be about 30* off so if its not anywhere near 113*...gotta take it apart. TDC was checked recently as I wanted to put a timing tape on the balancer. Used a piston stop and marked the stop point before and after TDC, etc.
