I have a 73 Dart Custom (A body) with a very hopped up 360 and the 2 row I have just doesn't cut it.... I need a OEM 3 row or an aluminum 3 row plus a fan shroud. Someone told me to go and get a 97 Lincoln Navigator radiator with the electric fans on it and that would cool very well. I open to suggestions. Thanks...

Had it recored with 3 row core and it NEVER gets hot ! Even sitting in traffic during the summertime. . . . just my two cents worth . . . Mark A12rag

The timing is perfect and all is new with the motor. The only thing I don't have is the fan shroud. I even had the radiator pressure tested and cleaned just to play it safe. The cars temp can run around 205-220...

What fan do you have, what temp stat & may I ask what is your timing. & WHEN does it get too hot, around town, out on the hiway. You might pull the stat for(1) day to see if it's restricted but I would guess as you mentioned more radiator. EDIT & the plugs look good(mixture) Last edited by RapidRobert; 01/28/09 08:51 PM. live every 24 hour block of time like it's your last day on earth

A 2 core aluminum radiator with either a proper fitting shroud/fan combo or a good electric setup should do the trick I used an electric fan from a late model T-bird on a Summit radiator and it was a perfect fit and the car would never get warm. Also used a mechanical fan/shroud combo on another car with a Summit radiator and with the a/c on in the middle of summer the car could sit and idle all day long with no problems.

With the shroud on the motor runs consistantly around 180-190 deg. I guess you can say that I'm a believer in the fan shroud. The air flow is impressive and it's not going all over the place as before. Thanks for all of the suggestions!
