65 Barracuda 187 code!!!

So my barracuda was broken in to last night. Luckily the only things they took were the stereo and the speakers so not too big of a deal. Still makes me absolutely angry because my luck is just terrible. I'm looking to go hei for my car. The only thing I'm concerned with is will it fit? The hei distributor looks pretty big.... Has anyone had any issues with fitment?
