If the motor has less than 1k miles on it, it'll probably run cooler with more miles. My 49 ran hotter than I liked (almost on the peg) for the first 600 miles & then starter to level off. Now it runs at around 170 until the outside temp gets above 90 then it goes up to about 190. And that's with 160 stats & an A/C condenser in front of the radiator.

It also helped when I got some new gauges that actually told me how hot it was.

I have 42k on it now & it runs better every day
