Radiator Size ????
The barracuda pictured above has a 408 stroker with 12-1 compression . Full exhaust and AC. It is running a factory 7 blade fan and a non AC factory dual core 22 inch 1967 50 year old radiator.
Before we installed the 408 it had a fresh 340 with a aluminum radiator huge high flow fan and no AC, You couldn't go 3 bocks and it was over 3/4 on the gauge . It was not the radiator. It was the fresh engine was built by an idiot at Koffels Engines. We got the receipts with the car from a member on this site. gtsjohn
Now it runs very cool and takes a while to warm up driven on the street with 391 gears. Sitting in traffic it never goes over 1/4 on the factory gauge. Any Aluminum radiator 22 inch is sufficient. You cannot flow any more then the hole in the rad support anyway unless you cut the hole bigger. Bad compression rings will make the car run hot. Also exhaust header or manifolds leaks will make it run lean.
If the radiator in the car is flowing water good and air moving freely its not the radiator. Did you do a compression leak down test on the cylinders. Check for vacuum leaks at the intake. Add an Air/fuel gauge. Before and after pictures.

Never over heated with the race motor and factory radiator for a non AC car with AC installed. Most times over heating has nothing to do with the radiator. But many times people put a big radiator in to fix a problem that is caused by something else.
