My 88 has never cooled well. I fixed the director flap below the crossmember. I need to get max air flow through the rad. It wouldn't call 205 a good temp on a 21 degree Celsius day. If I would have pushed 110 km/hr probably would have seen 215. This is a recored and cleaned up 34" wide A body 2 core Copper/Brass rad. A pic or part number would be helpful. I would like my 350 to run 200 max.

Below is the Champion aluminum radiator I use. It’s 2 row but there are two 1” tubes. Runs 171 on the highway regardless or ambient temp.

180 in stoplight traffic and Wide Open Throttle pulls on hot days.

200-210 idling for extended periods with air on.

Cools down quick. Keep in mind I have a different motor, electric fans, single turbo and my 3.5” wrapped exhaust runs right behind the radiator and in front of my drive pulleys. Tons of heat close to my radiator.

I have had multiple rads and fans in this car. Current is the big 2 core Copper Brass rad with Dodge Stratus fans on low. It never went above 195 in my 70 Cutlass, usually 170-180, no shroud and 4 blade fixed fan. The main issue is the highway temperature, should never go 215 with a 260. The 3 core Champion was so so at best with the 403, 185 with a 160 Robert Shaw thermostat, 230+ towing, even after dumping the underdrive pulleys. The no name aluminum 2 core with 1" tubes did well till the Mr Gasket no flow err I mean high flow thermostat started acting up a very short time in. Then it started leaking between thr cores, stop leak killed it's cooling was 235 after a short drive with 9.6 to 1 Olds 350. I agree on the large 2 core with 1" tubes or bigger being the best. I also tried a 5 and 7 blade fan with a new clutch and shroud. Been there and tried nearly everything.

I would put in a new aluminum rad and flush the system to get out all of the stop leak.
