Interesting Bob, thank you I hadn’t heard that before about Edelbrock. That modular design was quite a breakthrough and probably what gives the 4150 the advantage over other designs in that it is so tunable.

It’s also interesting that the Ford 4100 looks so much like a Holley except that the main body and float bowls are cast together.
