Unfortold "Carb Spacer" Power?

Funny to read this now. Back in the early 80's when I had my first V8 Barracuda I couldn't afford to do a lot of modifications. Changing from the 2v over to a 4v carb was too evpensive for me. What I ended up doing was getting a larger 2v off a 383. The carb was too big for my manifold so my shop teacher in high school and I made a 1" spacer that acted like another set of venturies allowing the air fuel to freely flow into the smaller manifold. We als had to make some offset studs as the bolt patterns were different. I also made an air cleaner that looked stock height so when you looked under the hood you had no idea. That car really ran great after that and no one could figure out why it ran so stout for a basically stock car. The Chevy guys hatted my car.
