That is your opinion. I was trying to actually answer his question. We don't know what either will cost him. I assume they are not new, but used. Have you run a Holley Street Dominator on a 318? They are not your oversized race single plane manifold. It will accept a square or spread bore carb. The Holley is similar to the 273 Commando intake, and to be honest, we really don't have enough info on the car, or intended usage, to make a real good recommendation anyway. I won't make general rules and there are a lot of things I consider before I do anything.
