Thread: Can't shed the heat after going up steep hills? Run a little hot. More capacity? SBC

Ok guys thanks for the helpful info. Here is what I found out so far.

Fan is a 7 blade steel fan and the water pump pulley is about 6 inches in diameter.


I checked the timing like you mentioned and it is 35 deg. BTDC (Advance) at idle. I pulled the line off of the vacuum advance and it is vacuum all the time. When I removed the line and plugged it the timing dropped to 5 deg. BTDC.
That being said the car never pings etc. and runs good.

Would the timing cause the running warm problem or not?

In the picture below the top line is the vacuum advance line going to the carb. If I need to change it to not have vacuum all of time does it go on the lower port on the carb? Should I change it to not have vacuum all the time and will this solve the running hot on hills? Will it cool the engine temps?

How will the car run without vacuum on the advance all the time?
