Only Flex-a-Lite fans that I've seen work are the Black Magic ones and the full size truck ones. You basically need about more than 3500 cfm+ , but the ratings are not standardized, so at times you just have to try or see it in action. .

At 3500 rpm I would think it would run hot on a long distance.
Can you try a taller tire to help gear ratio maybe. or a different gear? GT. |

Put a factory shroud on(its about 3" too narrow for this radiator), a 6 blade fan, swapped the 160 stat for a 180 stat, and it stays on the thermostat at 4000rpm on the freeway for extended runs...
I started off with the timing through the roof today(where I ended while testing with the electric fan setup), lowered it twice and it never changed the temp... Going to swap the fan with a derale 6 blade on Monday, and add a little more spacer to put the fan where i want it in the shroud, and will try it again on Tuesday when its warmer... At this point, I know its going in the right direction...It was climbing continuously after about a mile at 3500rpm on the freeway...You had to pull off to let it come back down, or it would climb till no mans land... |

Might have missed the correction, but worth stating here. The '68 timing cover was a combination of old and new. Still used the 8-bolt water pump with two plates that are not visible from the outside and the larger 4-bolt harmonic balancer. If either of the plates were missing the slow speed temps would also be through the roof.
Have a friend that went with a custom aluminum shroud/fan assembly and even with the flaps, the $1,250 assembly runs warmer on the freeway than his previous stock shroud and mechanical fan at speed.

What Brand Radiator? if they install brass chinese radiator dont waste time need to change the Radiator the core is to open and not radiate properly the heat!!!!! is like you connect hose with hose. OER have nice Made in USA brass radiators made by U.S Radiators in California. Good Luck.

No idea what brand the radiator is...
At this point, it looks like its going to be manageable now. |
