[DeTomaso] Brake booster vacuum

[Guido deTomaso]

Well, there's a lot you can get away with, doesn't make it right or wise.  Any 
flow through the PCV is going to reduce the available vacuum at the booster, 
plus the PVC passages in the carb aren't likely as free-flowing as a big hose 
barb in the manifold.

I don't think you'll see a factory set-up plumbed that way either.  Like you 
don't see factory vacuum advance plumbed to manifold vacuum often, if ever.

I agree with Will.  Why would it matter as they are drawing a vacuum 
from the same source either way.

Practically speaking, we set up a chapter member's Pantera with a "T" in 
view of his non-ported Strip Dominator and it hasn't been a problem.  
Real world data, not theory.
