G'day All, Wanted my 71 340 Demon to go faster. Couldn't afford a strip down, so I went bolt on stuff. Did the following - 750 Holley DP Elderbrock dual plane air gap performer inlet manifold. Bigger cam, (see cam card below). Doug's ceramic coated full length headers. Will be in the near future adding Elderbrock alloy heads & MSD dist. Opinions appreciated.
