My timing is set to 10 degrees BTC. This is according to a manual that I have. I just checked another book and it states 6 degrees BTC ???? All the same info: 289 HiPo, 4bbl, 4-speed...Only thing that is unknown is the ignition. I'm using an MSD-6A. What do you all have your timing set to and how do I tell if it's right without pulling the plugs after every run to see if it's running rich or whatever?????
