Camshaft help

I suppose the second carb could have a block-off plate under it, and a disabled throttle link.Nawwww, that won't work
Or you could disable all the secondaries.I would be up for trying the disabled secondaries and a staged, progressive linkage, but I imagine it would have distribution issues.
Or best of all a couple of really tiny 4bbls, like 390s.Yeah, you get the cool look, and driveability .
One of the problems I see with too much primary throttle area opening at once is that the car is very hard to drive smoothly at slow speeds. It gets real sensitive to gas pedal inputs.This is especially noticeable on a small-cammed, torquey V8. Maybe a 318 with a little lazy compression might be ok. I think it's certainly worth a try, especially since you already have the set-up,and since it's important to you. Still with a manual trans, it may be tricky.
