Not a fair comparison. The 71 Demon 340 is an all-original, restored stock 340 (other than purple "hemi grind cam) restored car w/ 3.55 rearend. We made it as stock/original as we could when we redid it. I think the exhaust pipes where they neck down going around the torsion bars are about 1-1/2" dia so this thing is really choked off. But that's ok because it's a car meant for cruising and taking to shows and having that type of fun. I tell people it's a sheep in wolf's clothing with it's Green Go color and flat black hood/scoops, stripes, etc.
