I just realized my 64 has a small block rad.

I was just considering today on upgrading my rad for a aluminum unit and just realized my rad is a small block rad? I didn't know that there was a difference? I never really had any overheating problems with the 383 but the temp would start to climb in stop and go traffic. With the new stroker motor I really don't think it's going to keep it cool. If it was a stock big block rad I think I would try it but I don't want to risk it with a small block rad. Just to confirm my rad has the upper hose on the left side of the cap this means it's a SB rad correct?
 
BB radiators upper hose goes on pass side of upper tank. You can see a flat spot where they put it. I recored small block radiator with 4 rows

but left hose inlet alone.
 
A clutch fan goes a long way. It made a huge difference on my car, and it doesn't even have a shroud, no room for one.
I got it thru summit, the company makes a clutch just for Mopars, something about the depth iirc.
Plus a new fan, starts with a D.
It's late, I'm tired and useless.
 
I ran the numbers on the rad in my 63 Polara with a big block. It's from a 65 small block car.
 
Some big blocks had the upper hose outlet on the left while some were on the right. However, all big block radiators had the lower inlet on the driver side. until 1973 or 74. Don't quote me on this but I think all small block radiators had the lower inlet on the passenger or right side.

My radiator was a 318 car lower inlet drivers side.
 
65 Dodge Coronet 318. When you say left do you passenger side or drivers side. To me left means drivers side.

Yes. Driver side is the left side for me also. I have only owned two small block cars. One with a 340 and one with a 360. Both had the lower inlet on the passenger side. Obviously, I'm not up to speed on the 318's. Another thing I was not aware of is the oil filter being in that location. That pic sure looks like a big block to me.
 
View attachment 803103 View attachment 803114 Just food for thought . If it is start to heat up with your current motor and you place the new stroker motor it will possible run hotter . I have seen this happen quite to often . Why not just get a new set up for cooling it . My latest car project has a 31x19 aluminum radiator that has 2 one inch tubes with 2 12 inch spal fans with a shroud that will pull over 2700cfm all the time . It came from Dillon Radiators in Rochester min. They have a web site on line . I had to clip the edges of the frame rail in order to get it in place . With a wiring kit you can control the fans manually or let them run when the motor heat calls for it to turn on . Doing this will allow you to remove the fan from your motor and free up a few hp . When I purchased mine I got it for $300.00 with free shipping on ebay from Dillon Rad. Just a thought . Hate to cook a new motor . P.S. Pics of radiator is in my 66 cuda frame rails do not need to be cut back that far , can take and send more pic,s if needed , John

I did go to aluminum heads, front water pump housing and a high flow water pump but I agree that it will probably run hotter with more HP and compression.
