Some more ideas
By Royce Peterson - 02/21/2002 10:08:04 AM; IP 205.188.200.199
Dave,
I agree with the other responses and have some other ideas regarding your situation :

1. Be sure you have a fan shroud installed. If you are using electric fans you probably do not have sufficient airflow, I tried this and it would not work on my car. A water pump driven fan pulls more CFM's. Flex fans pull more than clutch fans.

2. Several sizes of pulley are available for the water pump and crank. A smaller pulley on the water pump will move more water at low RPM.

3. Be sure to run a 50/50 mix of anti freeze and water. Pure anti freeze does not cool properly.

4. Very critical is to be sure you have enough initial timing. Check timing at idle, it should be at least 6 degrees before TDC with the vacuum advance line to the distributor removed and plugged. As much as 18 degrees may be necessary if you have a high overlap / long duration cam or low compression. Bottom line, advance it as far as possible without encountering detonation or pinging under full throttle acceleration.

5. If you are running a straight mechanical advance distributor you will likely not have enough advance at idle. Use a vacuum advance distributor and the temp at idle / low RPM will come down because the engine will have better (more accurate) timing under different loading conditions for street use. Wide open throttle operation is better on race engines with a straight mechanical setup but street engines really need some form of load controlled timing that is possible by using a vacuum advance or a knock sensor to control timing. Another way to approach this is to use a start retard attachment from MSD which will allow lots of initial advance but still let the car start at a retarded spark condition.
