Some more questions for Steve and the other experts here:
1. So even with a 255 and 260 int/exh duration, the 114 LSA vacuum signal is enough to offset that and promote a smoother idle/transition?
2. How much does the Redline "band-aid" of adding a third hole offset the negative effects of, say, using a 110 LSA cam?
3. Curious as to how many guys end up installing a vacuum pump to feed their power brakes?

Thanks!...Great thread BTW.

Dean,
These are great questions. At least now I have a clue about the '3rd hole' mystery.

Apparently, there are not many (or any) stroker Windsor, Weber- users out there, or 427 sized FE Webers in use that can shed light on this.
