I had quite a few, but the one in the pics is a Weiand three two barrel tunnel ram converted to dual 4s, with the insides ported and fogger nozzles drilled for but not used. LOL The top had dams installed too, much like the Direct Connection Engine Manual pages....

I ran an M1 intake on my Demon, I drove it in the middle of winter, the cold start drivability was truly awesome!
