Dewittes radiator
I have BB a Dewiites radiator module in my 69 BB.
I bought it from Zip corvette in 2009, the part number was RA 210.
It must have been discontinued, but I need to know the specs that I lost, what size tubes it has and how many rows it has

It is a two row core and most likely with 1.0" tubes. Take a zip tie and slide it into the core until it comes out the other side. IF the core is 2.25" thick, the tubes are 1.0". If the core is 2.75" thick, then the tubes are 1.25'.

Thankyou Tom, I will check the thickness, I have about 650 HP to the wheels, should the 1 inch tubes work, I want to take it up to 800hp.
I also had it tuned on a dino just to check that the timing and fuel was correct but it still runs about 212 deg. I have a Edelbrock high flow water pump with a high flow 180 deg thermostat so I am confused as to why it runs hot. The vette is modified so I have room for a thicker core if I have to.
Also I am Not running a heater, and still have the expansion tank installed in the stock location on the right fender skirt but do I need it with your radiators.
My engine
Big M block stroked only to 496ci
supercharger at 7 lbs
F.A.S.T. fuel injection
ECT.....

If you look at many of my past comments you will find I do not subscribe to the "more HP more Heat" theory of many. And by many I mean most people swear this is true.
To try and quash that belief I offer you the C7 corvette with factory 500 HP engines and a 1" thin single row radiator about 17 x 25.
You have one 2.25" thick that is 18.5 x 27.5". That's a whole lot of radiator.
Now someone is going to say, hey don't those C7's having cooling problems when tracking them? Yes, when they are driven full out, non-stop, extreme ambient temperatures and high RPM. But this argument does not work against my theory, it reinforces it.
It means when you drive that 500HP C7 around town like a normal car there is no cooling issue at all because you are not using 500 HP. Even if you do an occasional burn out here or there to impress your friends, the system has time to absorb that small HP surge and recover.
