Try putting the old carb back on and see if it makes a difference.
I had a Holley on my 260 and played with it for two years, never getting it to run right.
I finally replaced it with an Edelbrock, adjusted the idle screws and went on a 400 mile trip. That was in 1995 and I haven’t touched the carb since. It probably could use a rebuild, though, which is very simple on an Edelbrock compared to a Holley.
There are two types of people in the world — those who love Holleys and those who hate them. Guess where I fall.
Just my $0.02
