What’s the consensus for warm up procedure on carbureted longhood cars? I normally start mine & idle for a minute or two. Then drive conservatively until temp reaches 180deg. I've been told its good to idle a couple minutes with carbureted cars, but I've also been told it's best for a dry-sump car to turn the key, wait for oil pressure & go while keeping RPM's low to warm up. I'm in California, so temps are mild in the winter & hot in the summer. So I assume it would be best to start her up for 30 seconds & just go. Thoughts?
