I agree Dan, but I don't know what else it could be.
The carb is too rich the dizzy curve is stock, it's not timed to high.. I really think it is a combination of factors between the inner fenders not letting a whole lot hair out the winch blocking the grill and the condenser blocking the radiator. The radiator is a 3 core but is the big one the 545 part number.

idk what else to tell you other than you need to get that engine tuned by someone who really knows holley carbs because it honestly just sounds like a combo of bad timing and carb tuning causing the fall on it's face issue and the running way too damn hot problem. that's all i got man.
i ain't rite

if the radiator is too big the coolant will fly through it and not get cooled. i have seen this a few times. guys thing bigger is always better, and came to the shop with overheating problems. i would pop the hood and see a humongous 4 row truck radiator in a mustang. no thermostat, and running so hot it would snap crackle pop when shut down.
pull that monster out, put a "useless" 2 row rad and a 180 t-stat in it and send it on it's way.

I don't think that the radiator is too big. My crew has a 460 and I could not get it to run cool until I upgraded it to the 545 Modine #. The outlets of the radiator are the same diameter on either radiator, therefore in a closed loop system, it will move the same amount of water through there no matter what. It's the ammount of coolant in the radiator and surface area in of the radiator that makes the difference.
Now I may need to put a 180 thermostat in there. It definately couldn't hurt to try.
^^^^ While driving down the road after 15-20 miles,
^^^^ After returning to idle after the drive.
It continued to get hotter, I finally shoveled water through the fins of the radiator, and that cooled it off pretty quickly even if it was a little redneck... but it would slowly creep back up once I went to driving it again.

They are fine, It's an old condenser, but it came off of a 2 wheel drive, and was clean when I got it, and I cleaned it up more when I installed it. I really think I'm going to have really research ignition timing, including vacuum advance, centrifugal advance, and base advance. I have only messed with initial timing. I probably have a ignition system that is working against me a little bit. The other issue contributing is air restriction up to the radiator, and a restriction leaving the engine bay. (Rubber Inner fenders and such.)
The good news though is my transmission doesn't overheat anymore!
It is kind of pointless having a/c when I can't run it because it overheats... And I wouldn't bother with a/c but it get's HOT in the cab when I have to roll up the windows in the summertime when mudriding I'm not one of the types that likes bathing in mud every time..

Re in"Car"nation High Performance - Services
They can recurve ur distributor. Haven't used them myself YET, but have heard good about them.
I wouldn't be blaming the inner fenders n all that for air flow, I mean, a pickup, has to have better flow than a Van.
What kinda water pump you running again?

I was talking to a fellow today who has built a lot of 460's over the years, and is very savvy on them. He claims that when you bore one 60 over, you're asking for overheating problems. What does that sound like to ya'll?
