I run 25% antifreeze/ 75% water.
at the end of the feature my temp
is at about 235.
will running straight water help?

I run some anti-freeze to keep it from rusting the block .Have heard distilled water works better but I don't have a cooling problem.Clean the radiator good every week and have a shroud covering the whole radiator on the back side set up right. But alot of other things can cause the motor to run hot.

i never run straight water living up here in the great north. in the spring and fall it gets cold enough that the water could freeze. i had this to me after i built a nice 383...cracked the block cause i didnt drain the water in time. luckily it only cracked to the inside and a little JB weld took care of it. plus coolant lubes the water pump and prevents rust. you have some other cooling issues.

first off I would make sure you are not running lean on air fuel mixture. I have seen many times correcting a lean condition cure a hot running engine.

After that make sure you have a good fan, with good tight belts, and a good clean radiator. Make sure the fins are clean and straight. A shroud will make a big difference. If you run a shroud make sure your fan is positioned correctly in the shroud. If you are not running a shroud try to get your fan about a 1/2" away from the radiator. Make sure air can get to your radiator and isnt blocked by the hood/nose,etc.

Some swear by water wetter or purple ice etc. Run it with straight water and it lubes and protects your block, pump and radiator but it wont keep it from freezing. A lot of tracks have rules against using antifreeze because of spillage and ground contamination.

anti freeze will hold heat in longer then straight water

Check your timing.It should'nt be any more than 36 deg. total advanced.Just my opinon.
