Like what DVW said, ever try building a 409? It's more expensive than a hemi running the same et. Whereas most organizations will make concessions to anyone running a single 4 barrel 440 as long as it doesn't have a dominator on it and the car looks period correct. 422 runs a lot of Ford products because they're Ford guys and know how to build them and more importantly, know where to find cars and parts to build them.
