Hey experts need your advice.
My 56 has a 350 with high compresion pistons a mild cam etc 730 holley I have installed a MSD dizzy replacing the twin point mallory.
According to the previous owner the idle timing was set at 4deg btdc.
I set the timing at 4 with the MSD and on start it sounded like the cranck was going to break.
I then set the timing at 12 btdc started fine and then adjusted it to 10 btdc.
Took it for a spin and no pinging.
So my question is does the timeing at 10 deg btdc sound about right?
