hey Rebel... that radiator made my 440 run hot too.. thats why I went to autozone & got a remanufactured one... You either need to have it re-cored or get another one...

its definitelyt a problem with the radiator. when you say you took the thermostat out, you did replace it right?

Here is some info from Don at Moparchat.com.
Don has the website at the bottom with info on radiators and suggestions.
There is a couple of ways you can go.

1. A universal fit 19x26 radiator that would require welding on of the
brackets to get it to bolt in.
Outlets are upper passenger side and lower drivers.....#9617 $229.00
Universal mount all aluminum mounting kit......................$22.00

2. Direct replacement all aluminum ..........$300.00

Freight on either one would be $15.00 both in stock.

Both have tranny cooler fittings and a 8 plate oil cooler inside.

Both are 2 core, 1" oval tubes which will cool 25-75% better than a stock
radiator, 3 or 4 tubes aluminum radiators are not practical with 1" tubes as
the radiator would end up being almost 5" thick and would interfere with
most cooling fans. The whole Idea of using aluminum is to reduce the
overall weight, maintain size and improve cooling.

Either one of these radiators will cool your truck with no problem, as long
as you have an adequate fan system and a shroud to maintain efficiency.

Only 60% of the engine cooling is the responsibility of the radiator, 25%
comes from the oil and 15% from the air circulating through the engine
compartment. All of these need to work together to keep the engine cool.

If your concerned you can add a 10" to 16" pusher style electric fan and set
it up on a temp switch to come on at say 190*. So there's lot's of options
you can look at.

I took out a 19 x 24 Copper/brass radiator with 2 electric fans and replace
it with a 19 x 22 with 1 ten inch fan....dropped my 1/4 mile temp from 210
to 185, in fact if I leave the line at 180 it only picks up 5* whereas
before I would have to leave at 170 to keep it below 210, more than once my
engine would exceed 210* and I would have to stop at the end of the track
and cool it off for a few minutes to get back to the pits, not any more...it
could also be the "Cool" new paint job?
