Rich,
>From what you've described, it sounds like the cam is causing the lower
vacuum. You can reuse the TB gasket but soak it in some water for about
10-15 minutes first (thickens it up again) and then dry it and reinstall
it...upside down.

Bill,
If the TB is opened up a bit, vacuum runs up to around 20-25in. When I
release the throttle to let the rpm drops back to idle, the vacuum drops
down to around 5-8in., then slowly chokes itself down to around 5in.,
and then the engine stalls. It will sit and idle at a smooth 600-650rpm
(aside from the choppiness of the cam), and holds just about a dead on
11.25in. of vacuum, and doesn't deviate more than .25in.
I did reuse the old TB gasket, but it was only on for around 2Kmi. and
it looked ok. Guess I'll try cutting a new TB gasket and see if that
helps.
Any other ideas would be appreciated too.
Rich
