I help Holley on the forums, and that intake is really designed for bigger engines, power adder setups, and high-winding setups.

Correct. And the heat soak is a power killer over the composite ones (if your looking at the aluminum one).

I'm not saying you can't, but how? What size ports? What size cams? What kind of valve train? 7800 is no easy task.

It doesnt get any hotter then the plastic ones to the touch, to be honest. I expected it to get a lot warmer, but it isn't in direct contact with the hot parts of the engine, either, and gets a lot of airflow under it vs the plastic intakes literally sitting on the valley.
