I have a 72 custom with stock setup, automatic, 350 with AC. Can anyone suggest a radiator for the car, source for one at a good price. I am not looking for a top end unit. Just something that will do the job. As some know I have cooling issues and prob in the end will have to replace the radiator as part of the solution. I am also trying to source all the radiator cooling hoses. I found them all from GATES. I do not see any thing for the heater core hoses. Can GM hoses be had for this car?
Heater hoses can be got at local parts store. 5/8 and 3/4 sizes. You buy by the foot. Thats why your not finding an exact replacement.
I just swapped out my leaking original style brass radiator for a "new style" aluminum radiator with plastic tanks. I was a little nervous that it wouldn't cool as well as the original since it is so lightweight, but it actually seems to cool better. I like the looks of it compared to the flashy polished aluminum ones. You should be able to get one of these (either locally or shipped) for less than $100. I bought mine from Advance Auto, and it came out to a little over $80 with all the coupon codes/discounts. They are also available on RockAuto for similar money. My "CarQuest" brand radiator actually said Spectra Premium inside the box.

For what it's worth, my car was originally an A/C car but I removed it.
Here are all the specs on Summit: https://www.summitracing.com/parts/sgt-cu161 As far as I can tell it has one big core. I wouldn't get too hung up on chasing the highest number of cores; there's more to it like core size, number of fins per inch, etc.
Yes, it is listed as compatible with AC / HD cooling, and even 455 cars. It should be more than capable of cooling your car, assuming there are no other issues.
