The problem is that she won't idle at 900 due to the cam. She really loads up a stoplight at starts to choke at idle. 950 is better, I know it's not good for the tranny but what else can I do??
My biggest concern is this whistle/squeal I hear coming from the underside of the upper manifold (around the Edelbrock cover area). It doesn't make the noise right away...usually takes about 30 seconds after startup to occur. I tried WD40 and a torchtip but couldn't find a leak. Thanks for the tip on cleaning the valve....sounds like something I should try.

Second, clean out you idel air bypass with a heavy cleaner like a purple clean. I read a few post on this in the pass. An old post written by "MrClean" had some info in it as well.
