Radiator/Engine temp questions
The thermostat is a good idea for sure. I’ll get a temp gun too.
Im wondering if my radiator is too small. Maybe it’s for a 318 or 340 only?
all the V8's used the same radiator, cars with tow package, heavy duty police/taxi and AC got radiators with extra capacity. but, regardless of that your radiator should do the job just fine.
the widely different temp suggest that you may have a clogged up radiator. but because there are many different components to the cooling system this leaves a lot of variables to be considered.
things i would not do:
>buy a cheap *** aluminum radiator
>buy an expensive waterpump
>start swapping parts out whole sale.
things i would do:
>buy an IR gun
>test the thermostat or replace it
>run a radiator flush thru the system
>check the pulley diameters and calculated the waterpump ratio.
>ascertain that the pump is in correct working order
>check the timing-- too advanced or retarded can cause overheating
>check the fan to radiator distance, check the clutch if you have one
>install a shroud
