Carburetor and Distributor Vacuum

[Dick J <lsr_man@yahoo.com>]

Does anybody still run a carburetor?  
   
  I'm running a big block Chevy with an Accel ACC-9107 HEI distributor, Holley 
4150 HP Pro-Series 1000 CFM on an Edelbrock Torker single plane intake, and a 
Comp roller cam.  I have the distributor vacuum line connected to the vacuum 
fitting located at the back of the intake manifold under the carburetor base in 
the intake plenum.  The motor pulls well through lower gears, but falls flat in 
high gear and tends to pop back through the carburetor.  
   
  I've been told that I should not run the vacuum from the manifold.  One or 
two people told me not to connect the vacuum at all.  Should I connect the 
distributor vacuum somewhere on the carburetor? 
   
  This is strictly an LSR motor and not used on the street. 
   
  thanks
