    Default How to read timing pointer 350/5.7L chevy small block

    I am trying to check and reset the timing on my 1991 Suburban with the 5.7L engine. I hooked up the timing light and started checking the timing. Trick is, I have no idea how to read this timing pointer. I'm fairly certain that the large, wide V on the right hand side of the pointer is 0, but I'm not sure. The pointer appears to have markings on it, but I can't read them through the rust. I need to be at 0* BTDC, so if the V on the right is 0*, I can get away without cleaning it. Any ideas on cleaning the pointer up? It's not easily accessible because of the water pump, serpentine belt, etc.

    Here's my timing pointer:

    Wow, I expected someone to have piped up by now. I'm still uncertain on this.
