Both engines ran the same temps in their orig chassis. I did use straight anti freeze when replaced prabally should mix down to 50/50. Motor still shakes a little and when warm can hear a slight nock i think is fuel related. I would like to find a clear piture of vacuum layout to rule that part out .I think its a little warm because of a lean fuel condition chaged fuel filters next will check tank strainer.
