Here's one:
- Stg VI SFT A = Stage VIs w/ 266 at .050 x .600" on 108 SFT with ported Victor (no spacer, since it wouldn't fit under the old hood) and my Gold Claw carb set up with the 1.42" venturi sleeves

- Victor SR A = PRH Victors w/ 266 x .050 x .650" on 108 Solid Roller w/ mildy modified Trick Flow intake, 1" Super Sucker spacer, and the QFT 1.52 v downleg carb

I've got the raw #s, but thought the graph presented better. The thing that most stands out -- for me, at least -- is this wasn't simply a gain on the top end. It pretty much gained everywhere across the test RPM range.
