it's getting up there in temp. But as i said some enginw's will run at 275 and higher and some will nevers see above 250.

Engines are like people they have there own personality's. Some like to run hot and some like to run cold for some engines yes 275 is hot anf for some it it normal if not a little cold. But 275 weather it being hot or cold can only be compared to what you have experience with. I have seen engines run 300 degrees before and have more then 6 gallons through them and there still running good. But i also have seen the same for 250 and lower. But basically as i said it all depends on what you engines personality's is and weather it has a personality issue or not.

When i say it has a personality issue is if it runs at any temp higher then 280 but as long as your not running your engine lean and you reach 275 then your fine and really shouldn't worry about it. Just tune for performance

But the answer to your question is yes and no.
