Radiator/Engine temp questions

Personally I would not go for an aluminum radiator.

The OEM / OEM style copper brass will be your best choice.

Radiators can be made for standard cooling, HD cooling etc

It's all in the tub size, number of tubes, and fins per inch (RRR mentioned this)

The only place heat is transfered is at the contact points between fins and tubes, the more contact points (ie surface area) the more heat that can be transfered.

As pointed out before, if you have a 195 thermostat 200 to 210 might be normal.


My engine (Stock 67 273 2 BBL) runs hotter at 75 mph then I would like. At 65 it comes down to normal.

I have tried water wetter, made no difference.

I tried high flow thermostat, made no difference

I have a few more things to try.

Good luck
