Ok, one more question on the Holley jetting.

and 10 at the light throttle cruise

Wow Greg. My gut reaction is WTH?
IMO At light throttle cruising the engine should be pulling a heck of a lot harder than that.
I'd expect a minimum or 14"Hg and as high as 18"Hg depending on rpm, speed and whether a slight up downhill.
