I have a mild 355 (330hp) I am getting ready to swap dizzys in it. I checked my advance now and it is like at 20 deg BTDC seems really high starts fine and runs good. When I install new dist. should I try and lower that or go with close to the same? Also not sure if the timeing pointer is correct but have no reason to doubt it.

Thanks

12 is the factory setting I believe.
