Man. I had no idea that Edelbrock had such a bad rap. I feel like I must be a complete idiot and so ignorant that I can't tell that the ones I have aren't working well.
Anyway. I got my sister to get the intake casting number 3844472. I looked it up and all it says is 4bbl carb. I guess I'll just have to wait and measure the bolt spacing. Just means I can't have parts waiting for me when I get there tomorrow.
