Having two fuel tables / two spark tables (near idle / off idle) is awesome for tuning an aftermarket camshaft!:thumbsup:

Hi Dave,
Just a quick note to all on this intake. If you add a TWO Inch spacer between the lower and upper intake half, it has a significant power increase. The reason I know is the Head Big Block Engine calibrator told me this when I was selecting my big block intake/system for my truck. This intake was selected because it fit in the G-Van. I bought a Az Spd and Marine intake, which was the first Alum Marine intake for the big block. A one inch spacer adds power on this intake.
