Fabbed a carb spacer to go under the carb spacer, and it worked. You can in fact use the Edelbrock intake manifold with a 4100 carb.
If I can do it, ANYONE CAN!
Bill White still argues that the stock manifold is better than the Edelbrock, but what's done is done. I can finally work on something else in my car.
