I heven't done the full on assessment yet. It does seem to run a touch hotter than the other motor but that could be down to any of three variables. I't's not the same temp sender and it's not the same thermostat. Nor is it the same water pump but I don't think that's an issue. The main thing is that it doesn't overheat and my rather clean viscous fan still does the business.
The engine has a noticeable increase in lower end pick up which is what you'd expect from a street port and it pulls strong thru to 6K. Haven't tried more than that yet. And the front end has developed a vibration at around 75 mph which I hope is only an inner wheel weight as all the outer ones are still there. May be time to look at the ball joints otherwise.
So I've dome around 150 mainly motorway miles with a healthy dose of sitting in traffic on a reasonably hot day and all is good so far. So I took TWiR to a little car show yesterday ...
