I went with the stock 22” 3 row radiator and a fan shroud from a A-body with a/c. Use the stock pulleys too. My M-code car would run at about 185 in any weather condition.

I know the outlet is larger 1-3/4 dia for the BB vs 1-1/2 for the SB, does anyone know if from factory it was 2 or 3 core?

Be sure to use the correct FAN, PULLEYS, and WATERPUMP. it is a cooling system and all the parts have to work together. Look in the parts book for part numbers and google from there.

I think that you’re right about the neck size. I seem to remember that I used the top tank from a 383 B-body when I had my radiator built.

I’m pretty sure that Glen Ray has never made an 065 rad. 1968 033, yes. My back up 065 is a Glen Ray new in box that I was told was made from an NOS top tank.

3 core.

3 core.

How about that, (for all the naysayer out there) the factory cooled a 440 with a 22" 3 core radiator, a mechanical fan, 190 deg thermostat (160 is NOT recommended).

(sarcasm to follow!)

How can that be???? Only an aluminum radiator with electric fans and 2 x 1 inch cores could possibly do the job!

The same radiator was used for the 426 Hemi. I ran my mild 383 as a daily driver for years with no cooling issues.

Kind of odd to me. But even some b body big block cars had 22 inch radiators. And some small block b body cars had the 26. Whether the car had AC or not seems to be more of the deciding factor than engine size.
I looked at Glen Rays website and did not see the big block a body radiators listed. But I would imagine it's spendy. But you would never have to buy another.
I called a few years ago about re coring a radiator for big block use. They maybe Bob said cooling built big block with 3 row radiator was non issue.

Oh they are spendy, I had to replace mine after some creep ripped mine off for scrap copper. Found a core here and had it recored, all good now But that is what I had, and mine is an original big block car, so you pay your money. Not a fan of aluminum radiators, mainly for looks.
