<strong>Awsom: It has always wanted to overheat when not getting moving air flow. I am running a 160 degree thermostat with 40 BELOW cooling additive which seemed to help.

Have you heard of any luck using the shiny shroud that JC Whintey sells. I am wondering the benefit of going all electric and eliminating the flex fan?? Any ideas??

Overheating is a combination of factors as a general rule, not just 1 thing.

1) always use preformed hoses, not the universal flex hoses. Take a piece of coat hanger, make a pattern and find a hose like the pattern. Always use a bottom hose with the spring in it to reduce risk of the hose closeing up and stopping flow.

2) run as large a mechanical fan as possible with lots of deflection..... Summit sells "stock car fans...15, 16, 17 " and more.

3) a shroud will help.

4) the timing may be too high....or off.

5) always use a distributor with a vaccum advance.

6) the carb may be too lean (the jetting)

7) Sometimes a too low themostat does not let the water stay in the radiator long enough to cool....move up to at least a 180 (I always use 195..with no problems)

8) Better water pump. Flow Kooler plate installed on the water impeller can reduce temps by 30 degrees. Edelbrock has a super good aluminum pump ($150 or so)

All of this still requires a good radiator with cooling ability for a 350.
