Currently running an NOS 370-195 Rob Shaw. It's too hot, I think this is the cause of my dieseling and run on issues at shutdown. Heads are getting too hot. What's the preferred temp especially for low speed crawling. I'm running the HD clutch fan. Not currently overheating. My gauge runs at 1/2 way most often. I'm getting either the Milodon 16405 or 16406. I can get the 16405 for $57 Cdn on amazon but they don't have the 16406 that on is $70 Cdn shipped from summit. IHPA has no stock of the 160 or 180s only 195.
