Re: Almost back in business



I took the stat out today.  I had it installed correctly.  I tested both the new stat and the old one to see that they opened correctly.  Both worked like they should.  When comparing the two side by side I noticed that the new stat has a smaller opening.  It was 3/4" as compared to 1", which means it is nearly 50% smaller.  One thing I had done previously trying to work on the cooling issue was to install a higher volume water pump.  So I wonder if the two components together were the problem.  Maybe causing the pump to cavitate.

I installed the old stat and also drilled an 1/8" hole in the flange to make sure I didn't get an air bubble in the system.  Since it was kind of rainy out today I didn't drive the car but I let it idle in the garage for about 30 minutes at 1000 rpm.  The temp did come up a little higher than it used to but not quite as high as yesterday.  At the highest temp the reading on the upper hose just above the stat housing was 195* and the bottom hose where it exits the radiator was 145*.  This is with the 180* stat.  I didn't get any of the percolating etc. that I did yesterday.  

I'm attaching a two pictures of the temp gauge,one showing where it normally ran on a cool day, the other shows how high it got today before I turned it off.  I've reduced the size of the pictures.

I spent the last two days dropping my 440 back into the Sport Fury.  It has been sitting for the last 14 months due to a detonation problem and a broken piston.  The long time lapse was due to a machinist who had it for more than eight months without doing any work on it.  So I finally just went and picked it up.  Rich K. and Dodger recommended a machinist who is a Mopar guy, but he is also busy.  
The top land broke off of one piston and upon inspection discovered that, that had produced a big dent in the cylinder wall, which could result in a crack.  So it was recommended to sleeve that cylinder, which then means the others have to be bored.  As it was explained to me the cylinders adjacent to the sleeved one get distorted in the process so they need to be bored to bring them back to round so all the others need to be bored as well.
But at last it is ready.  As luck would have it the weather is cooperating and it hasn't been too cold in my unheated garage.  So if everything goes to plan I should be able to fire it up tomorrow.  And the weatherman is forecasting temps in the 50's for the next couple days so I might even be able to go for a bit of a cruise.  Wish me luck.
