If the engine produces less vacuum than that, the systems can still function, but getting them to work properly requires a lot of manual tuning, outside of what is easily achieved through the handhelds. If you're getting into that large of a cam, you would really be better served with a different offering. If it has to be a TBI system, I'd look at the holley terminator. Tuning is more involved but that system has more capability.
