Back in the early 70s I did an A-B swap at Hampton Raceway between the stock 69 440 intake and an Edelbrock CH4B, the car ran identical to the hundredth. The engine was a bracket race 426 street wedge with a Holley 4779. I did a lot of flow work with a stock 2100 intake and was very impressed how much better it was than the AVS intake.
