stalling out

99% time this issue is either tuning or a carb that needs a rebuild. A new distributor won't probably fix the issue. Just start at 10-12 degrees initial. Wouldn't worry about total until you get it to idle. If you don't feel you have a vacuum leak then you need to tune the carb to get it on the idle circuit. Do you know how to tune a holley? Make sure the mixture screws are clear & working. Then adjust for best vacuum with a gauge. There's more but this is how I'd start to tune a new combo.
