Oil temp!!!
 

Built a new 421 sbc. 1/2 hardblocked. Water temp is good but oil temp seems a little hot around 250 to 260 degrees. Is this a result of the hardblock? This is a street motor and i am about to switch to synthetic oil does anyone have a take on this? I am hoping that this is normal. Thanks for any help or input.

ive heard guys said that with a half filled block oil temps rise,so naturally an oil cooler would be an easy soulution,good luck should be ok :)

x2 on oil cooler.
The oil is pulling the heat away from the bottom of the block that the water was doing before.
