Here's a cold start of my '69 Mustang fastback with a 351-4V Cleveland and glasspack mufflers. It was 27 degrees Fahrenheit and about two weeks since I last had it running.
The choke's been a bit stubborn since I had the carb rebuilt and I have to keep my foot on the gas for a couple minutes or it stalls out. (I edited out some boring warming-up footage.)
Quite a bit of smoke as it warms up, which eventually dissipates (see after last edit) and a little poppy when revving. May just ditch that Holley come spring.
