No start after rebuilt motor swap!

[Dr.Evil]

Well its running good, no CE lights :****: Got about 30 miles on it and its runnin like a champ! But if I rev it in neutral, when the RPMs drop back down it dies. Its like it is starving for air. Would the cams or lightweight flywheel cause this? A vaccumm leak? Ill hook up the tweecer tomorrow and see if that tells me anything. Just thought I would see if this has happened to anyone else.

My SHO started to act like this when I first installed my 8-lb. FW. After a while of driving, it seems that the computer finally adjusted for the lighter weight flywheel and it no longer dies when the RPM's drop. And this was with stock cams, so I'm sure that aftermarket cams would only increase the problem. Did you raise the idle speed with the TwEECer?
