Sorry, COMPLETELY incorrect. The fan should be in the narrow area of the shroud, and I've seen factory cars--Chibbys and Frauds--where the factory fan was about a FOOT from the radiator.

IN FACT putting the fan so close may actually HURT airflow, because it won't be pulling air from the outside cores, and may cause turbulance which may just plain reduce airflow.


Also, there is NO reason to re-engineer thermostats. A 'new' stat CAN be bad, and I'm not sure of quality control anymore, but in the days I used to roar around town, overheating was NEVER at the top of the list. I ran factory 190-195 stats, and this was when I was in S Cal.
