Thanks Steve, I had scanned the EMAIL archives and saw references to the
Boss 302 spacer. The archives looked like they had indicated that the Boss
spacer would fit under the hood with a 4BBL carb but I could not tell for
sure.
I have an F4B on my motor. So I'm not currently shopping for a manifold.
But on that topic has anyone seen the Edelbrock "Air Gap" manifold? It is
essentially a performer with the runners isolated from the oil galley cover.
It is supposed to offer heat isolation and thus a denser charge availability
under certain circumstances. One article I saw showed a several HP gain
(around 10 actually) under steady high load conditions (dyno pulls).
