rebuilt n/a engine won't stay running below 3000 rpm

I just put a newly rebilt engine from espritauto@nucleus.com in Calgary Canada into my 88 normally aspirated and I can't get the engine to run under 3000 rpm. Any ideas?

Is your cat clogged? If it is it will smoke like crazy when it is warmed up and smells like crap...

Vacuum leak. If it won't run under 3000, that sounds like several small leaks or 1 big one.
