    I have a built 383 and it runs at 160 deg. all the time with a 93 4.3 litre s-10 aluminum rad. I have a mechanical fan and twin electric fans without electric fans it runs at 180 deg. These rads are cheap and easy to come by.

    Good Luck

    If you need to buy a new one the best all around radiator is probably the late 80's aluminium Corvette (it's a bolt-in). Reasonably priced around $150 at Autozone.

    The stock 4.3 radiator is constructed the exact same way as the corvett radiator, only it's bigger. They are both single core (same thickness) aluminum radiators with platic tanks. The S10 radiator will therefor offer better cooling, contrary to popular belief. However, it is more difficult to recess into the support if you are going to be mounting it in the forward position.

    To answer you question, I am running the 4.3 radiator with the flexalite 210 fans (perfect fit BTW) and a 160 stat, and do not have any cooling issues other than it taking a while to come up to operating temp.

    i use rodney red custom made radiators from evansville, indiana and he send you a sheet to get measurments so you can make them fit your ride and they are aluminum so they cool the best. they cost as much as buying a new radiator from any parts store or at least they did when i bought from him

    The 4.3 radiator for the S10 is 15/16" to 1" thick depending where you buy it & the 89 Corvette radiator is a couple inches narrower but it is 1 1/4" thick so it cools a little better.

    way to bring up a dead thread and put in bad information.

    my 4.3L radiator is 1 3/8" thick and has 16 fins per inch.
