Edelbrock 1406 whistling

I didn't mean that he should attempt milling his intake down himself with a piece of wood and some sand paper.

what I was getting at was doing it just enough to leave sand marks in the aluminum so he can see if there are any high or low spots.

then if so, he could have it professionally straightened out or invest in a new intake or if he wanted to....he COULD continue sanding until it was flat.

might not be the best option if that is the case....but an option.
