Fram filter is THE WORST restriction you can have behind a pump. Took two Holley Blues and two Fram filters to go 10.80's in my buddies' Chevelle. One Holley Black (replacement for the Blue) and one K&N Billet filter and I have gone 10.60's.
If you don't believe me, do the math on what the Fram flows and then look at the rest of the filters out there. The Fram is the worst, just like their oil filters.
