318 rpm drops to 400 in gear WHY???

I hope you've got a good compression ratio going with that cam. I made that mistake once and won't do it again. Also, as someone else mentioned.....32 degrees @ idle? I've actually heard about people drilling small holes in their primary throttle plates to get more air flowing through (because of the low vacuum) so they wouldn't have to crack the throttle open so wide and start getting the booster venturis dribbling. Maybe you could research that.
