Id say less on the weight and more on the efficiency. I read that stock E7s flow in the 150 cfm range. For comparison, my box-stock TFS 170s flow 250 cfm. I'm itching to slap them on.

Has anyone that posted a number got a nice set of heads and intake, as in better than a GT40? I don't think you'd see a difference in stop/go traffic with them, but I'd bet highway would be a noticeable difference.

When I get mine back on the road I will have some data to compare.

Mine is 7 mph faster, but that isn't a direct correlation. I read 1.1 miles for every 1 mile actually traveled. My car read 302.7 miles, which translated to 275.2 miles. I burned 14.2 gallons going from Savannah to Jacksonville and back. Comes out to 19.4 mpg. That's running a 306 block, GT40P heads, Explorer Intake, F303 cam and 4.10 gears.
