Helping out a friend who bought a nice old and slightly moldy RV. Slapped an alternator on it tonight, which was such a delight compared to my usual n54 BMW stuff. When I started it up I noticed a pretty high idle, probably 1400 rpm.
I popped off the doghouse and looked around the carb. I haven't worked on anything like this in over 25 years. The one thing I did observe is that the throttle sat above the idle set screw by a couple millimeters. If I pulled the throttle closed, it would calm down, but only maybe to 1000 rpm, still pretty fast.
Could this be as simple as cleaning the carb up a bit? It seemed more mechanical than anything else, simply that the throttle isn't closing. I didn't get into vacuum lines or anything like that yet.
I have to say it's amazing how smooth it runs. I've been driving BMWs for 20 years, but that SBC just sounds so sweet.
