Thread: Can engine temp be to cold?

Tweet

My truck alway run at 200° when I tore down the engine and founded that the cylinder wall had very little wear and everything else looked great so I did build it back to Std and still running great. So I believed the hotter the engine run will have lot less wear that the cooler engine.

have a 195 in both my carb'd 302's. Motor runs better, less wear. The crap that passes for fuel these days needs all the help it can get.

Its been my experience in the past...you want to run the engine at the higher operating temperature like 180+ just because the cylinder head pressure will be higher which will also maintain a more stable compression.....ex. rings will be expanded more. But we (friends at strip) found that obviously you can go to high. I like the 180+ and had no problem running a destroked 400 with 12.5 to 1 compression all day at the track but my cooling system was up to par.

180 - 200 would be best. I agree with Fitzwell, piss poor gas they sell today won't fully detonate in a colder engine.
