Yeah, it's holding pressure. I had the radiator checked by a professional and he said the radiator is in excellent condition. My big question is......I've changed nothing except a rebuild and .030 over, why would it need a shroud now if it didn't need one when it was manufactured?
Don't hijack my post dude, I'm on a mission. haha!!!

Right now I have the electric fan on it. It runs noticeably cooler when the temp outside is below 90, so I stuck with it. I've tried the stock setup and just about every combination. NOT a shroud issue... I wish it was that simple....
You need a better fan and a shroud. My stock cooling system can idle all day long with the AC cranking. You need a 7 blade fan and shroud, I'm telling you.
How much initial timing do you have and what is the total?

I too have the overheating problem on my newly rebuilt 383. My Bee was manufactured without a shroud. Certainly these cars built without shrouds were engineered to operate in the proper heat range. According to a recent publication by Paul Hurd....cars manufactured with the 22" radiator only received shrouds when they were equipped with A/C or the MAX COOL option. 
That would only be true if the car was an A body , everything else with A/C and/or MAX COOL had a 26" radiator

The lost secret is the impeller blades on AC cars were smaller and moved less water per revolution than the standard pump, and this was necessary because the pulley diameters changed for AC cars and they turned the pump much faster than non AC cars. The correct answer is the non ac pump impellers 8 fins as I remember and a towing fan 7 blade fixed hub) And the correct diameter pulleys for the crank and water pump. Everything must match... a 4 row copper/brass radiator will help as well.

The only thing that sticks out to me is that you seem to have better luck when the timing is "off"- pointing to the TDC mark being off.
I would also look in the radiator again. I had a car that was cooking itself to death. I had the radiator boiled out and it did great- got lots of sand out.
All was well until I raced a guy for several miles one night on the interstate. Car boiled over like you would expect. The the next day it was overheating again like before. I looked over all sorts of stuff and happened to look down the neck as I went to refill it again. MORE sand had been pushed out.
I want my fair share

Well, after doing some research and listening to your suggestions, I decided to check out the timing. So, I did the following:
I put the #1 to TDC by rotating the engine until the comp stroke and aligned on the balancer to exact TDC. I confirmed it was at TDC by removing the valve covers and noticed the intake/exhaust rockers were loose.
Pulled out the distributor and saw something interesting. The gear drive was not exactly in line with the camshaft. It was off one tooth. I put it in line with the camshaft, made absolute the rotor was pointing to #1 and put back together.
I then put a mark on the balancer per the previous recommendation, and used that to set timing.
After doing all this, I did notice the car ran considerably smoother and had a lot of power. No pinging or anything. I was hoping it would run cooler, which it did stay under 200 while having it running in the garage for about 15 minutes. Tomorrow I'm taking it out for my morning commute to see how it holds up.
I didn't put the thermostat back in yet, but I don't think this will have anything to do while it's running at/above operating temp, right? I'm putting it back in tomorrow anyway since I didn't notice any difference with it out or in....

UNLESS the balancer mark was off, you basicly changed nothing Quote:
