Your tri-pwer setup should bolt right up. I did that to a 69 400 from an earlier year 389 and it worked pretty good till I got fed up with the constant adjustments to keep it running good as I only re-built the center carb. Went back to a 650cfm holley and actually got better performance and drivability.

make sure the upper radiator hose doesnt go upwards before entering the intake. I had a similar problem> I had an air pocket and the water wasnt flowing enough. Good luck anyway.

I had my 389 rebuilt and it overheated and vapor locked after it warmed up. I could only drive it about 1/2 miles and it would vapor lock, i would let it cool down and it would start again. What I found out was the intake gaskets cross flow under the carb were wide open, wrong intake gaskets. I put the correct ones in that had the middle port blocked off (I have an electric choke but if you have a thermo choke you will need to install the ones with a very small hole) and the vapor lock up stopped. Bottom line when I checked the intake mantifold under the carb was hotter than the exhaust mantifold. You might want to look at that for the vapor locking.
