A-Body 440 cooling problem

Thanks guys,
You all are a pretty sharp bunch...Very good advice...and I thank you.
The fan was pretty heavy and the belt (new notched) didn't wrap very much of the pulley. It started to squeel around 2000 rpm (guessing) and did it every shift. I am also guessing that the clutch fan I replaced it with may of been a bad one It has silicone leaking from the heat spring. I figured that a flex fan would do the same squeeling...maybe not. The shroud is another problem. My fan seems to be in the center of a 28 X 18 radiator. Most shrouds seem to be off set. I saw a steel truck shroud that looked pretty close ,but missed it. I'm not sure the builder used the right K-Frame for the 440 install. I saw some welding on the motor mounts that wasn't very good.
The timing is also an issue. I will be checking it this Wed at a friends shop ( don't have a total advance light) I may have it too retarded because any more advanced...it doesn't like to start...it bucks a few slow revs when warmed up, then kicks off. (new starter and new gell battery 800cca). (manual choke...never used) The vacuum advance is disconected..might of been re-weighted? This friend of a friend is a mopar drag racer...hope to learn new stuff there this Wed.
Thanks for the very helpfull suggestions and advice. Good stuff to think about. Thanks, Bud
