    Go to Autozone and tell them you've got an '84 Chevy truck K10 1/2 ton 2wd auto trans with standard cooling and you can get a 3 core for $150. That's the one I've got. The manual trans one is $167 for the same 3 core. A 4 core is $240 and will be listed on the same page as a, "Heat buster". I think the 3 core is plenty. All of them will have a lifetime warranty.

    I got a Modine #730...That is the listing for a 1987 K30 with a 454. Even though I have a MT, I got a rad for a truck with an AT so I can use the tranny cooler fitting fo stuff like PS fluid or oil...oh you will need to buy/make/borrow/steal 4 new rad. cushions for a 4-core...

    I recall having a hard time finding reasonably priced 4 core applications, so I bought the 3 core.

    Sure, it'd be plenty. Airflow is more important than a thicker radiator.

    Even a 7 core radiator isn't going to cool if it's clogged.

    88 454 had external oil cooler and it's a 4 core. I just bought one. www.Radiators.com and www.raditor.com both have the modine for around $170 might get a discount with one since your a member. Check the venders list.

    [/ QUOTE ]
    I have a built 406 and my 3 core is enough, but just enough. I have to watch the temp when I'm pulling hard in the mountains when there isn't a lot of air flow. I would suggest an aluminum rad. they cool better than a 4 core and are cheaper.

    You said it yourself, "There isn't a lot of airflow."

    Use the right fan and you won't have cooling problems. Air conditioning makes it worse too, but I'd bet that a 3 core could even cool a 454 without A/C in the hottest of weather with the proper airflow.

    The proper coolant mixture helps as well.

    [/ QUOTE ] I have A/C and even in 100degree weather in stop/go traffic it usually doesn't get much higher than about 200 degrees. I JUST have problems in the mountains with a heavy load and warm weather. Otherwise it runs about 160 degrees.

    too bad one of my 77-79 van auto radiators would fit it, i have tow nice four core ones,

    thanks
