I am stepping up to a larger carb and might need a new intake manifold unless I decide to carve out the existing one. I looked around and checked out all the aftermarket ones, but I think I might kill myself before I pay $70+ for a small piece of metal plate and rubber. I had a few things in mind, but I was just wondering how you guys running larger carbs dealt with the issue either by buying an aftermarket or by making your own.
