I got this thing running today, however it idles like crap. I will try adjusting it a bit more on Monday, but I am wondering if I might need a slightly upgraded cam to handle the idle? I don't know if I am over feeding the engine or not. I can't find the CFM rating for Holley 1904's anywhere. I also still have the stock exhaust manifold on it. I haven't made headers for it yet. I did switch to a glass pack which should cut down on some of my back pressure also the tail pipe is not connected which eliminates a lot of curves, namely the one over the rear axle tube....I still have a feeling that this may not be enough. I just want to not have to side step the brake to keep it running at red lights.
