My Edelbrock B4B is an original from the early 70s, back when you kept your parts secret. It originally sat on the Reynolds Buick White Stage 2 car, and the markings were chiseled off, so the competition didn't know your secrets. I had my old room mate sand blast it at work right before they changed the blasting grit, so it was nice and worn down. It was more like glass beading at that point. So the intake has a smooth satin finish, and no markings, except some faint shallow divots where the logo and B4B were. Super sleeper. Well, except for the rumble.......
If you have the room, a 1" spacer might be worth 8-10 horses on the upper end. Mine has one, and I compensated with a quality drop base air cleaner assembly. Still clears the stock GS hood with a 4" tall filter. You can buy one that is also a heat shield insulator so you carb stays cooler.
