Re: LT4 HOT CAM DO I NEED BIGGER CAM

That's the "Bigger is Better" way of thinking at work. Whether you REALLY need more cam or not boils down to what your plans are for the car. First, decide on how the car will most often be used, then decided.

Much more cam than what you have will begin to introduce some negative side effects, like worsened idle quality, reduced gas mileage, lower vacuum (which can effect the power brakes) etc.

Which intake? Carb way too small.
