Hello to everyone. I hope you all can give me some advise, because I've reached then end of my technical expertise. Here's the situation:

1965 Ford Mustang with a 302 small block. Had the short block and the heads professionally rebuilt, but assembled everything myself. Used mostly aftermarket parts (competition cams, eldebrock dual plane manifold, Holly 4150 street avenger 650 carb, Pertronix HEI distrubutor. Also had the C4 transmission professionally rebult as well.

Anyway got everything back in the car, and I got the engine running. But I am having 2 major issues that I cannot seem to resolve.

First, the engine is idling way to fast (I don't have a tach hooked up, but it sounds well over 3000 rpm). I have backed out the idle screw all the way, and also set the fast idle screw on the carb back some to no avail. I'm not sure what else can be done, or why it would be idling as fast as it is.

Secondly, the transmission will not engange when the car is put in gear. It is difficult to check the fluid level on the transmission since the car is supposed to be idling in park to check the level, but I know the capacity of the trasmission is 9 to 10 quarts according to mustang book. It has 9 quarts in it now, and it still does not move when the transmission is placed in any gear (it does make a slight rattling noise when put in "reverse", which is not very reassuring.) Oh, yes, the emergency brake IS disengaged, just in case you were thinking that. :-)

Anyway, I'd be glad to offer any information that you would want that I did not provide, but at this point I'm about to just have the car towed down to a mechanic, as I can't think of what might be causing these issues. Any insight anyone might have would be greatly appreciated.
