Sitting still on a 93 degree day 195 is as hot as it gets get over 2,500 rpm and 210-220 is what it hits with a 190 degree stat . Milodon water pump stock pump high flow non high flow same thing .

tried straight watter 50/50 mix and with coolant additives same thing . I was told by Jegs who i got the crate engine from 2 months ago that this is normal that a 350 chevy runs 200-220 degrees with no problem bull is what i say i want no more then 190 . Even in the rain on a 64 degree day it runs 210 degrees .

Jegs told me it was timing so i checked 18 degrees advanced at idle with a super charger and 38 degrees at full advance . The fuel mixture isnt lean im running fat 12 to 1 air to fuel a bit fat but better then burnt valves .
why 18 degrees base timing? thats hi.
