engine vacuum (non lsr)

["Paul Bland" <paul.blandavon@btinternet.com>]

List, can anybody help me on a project I'm working on? on a Rootes blown V8
motor, what sort of vacuum would you see inside the injector hat if you closed
the throttle at full speed? There's probably a really simple answer, but it
escapes me.
Cheers, Paul in the UK, where for a change it's not raining!
