Thanks George and others for the help fixing the cooling problem with my 67 Bird. I quit driving it for about ten years thinking I had a motor or head problem (it all started when I upgraded to a set of #62 heads because mine were shot during a rebuild. The Autozone water pump every one said to get is also pot luck as I ran into a stamped. I ended up using the Milodon which I bought before I read this post, but the cast impeller was only 1 1/2" long. I changed my pulley to a 6" from an 8" and I think the biggest help at idle was buying a junk yard 7 blade and new clutch. Everyone thinks a clutch is good if it has a little drag but that is not true. I tried the junk yard clutch that had drag and it didn't move much air. I replaced the clutch and it was 300% better. I also closed the water pump gap from the original 1/8" gap which I think solved the highway heating problem. I used to run 210 highway and 240 and climbing at idle. I now run 180-190 highway and not over 200 idle. Thanks for the help. I will replace the water pump with a full 2" vane cast when I get one.
Does anyone ever run into carb heating problems? Now that the motor stays cool, the carb still gets pretty hot from radiant heat and seems to stall when starting from an idle. Any help out there for this?
I am getting rid of the headers and going with Ram Air III long branch. This may help get rid of some of the heat and definatley the exhaust leaks.
