I do have a 418 short deck r3 but its 13:1 and dont really want to buy race gas for the whole trip. The car is fairly lightened. No back seat or heater. Most of the brackets are gone or swiss cheesed. Usually run it with around 7 to 10 gallons of fuel. Would like to put a set of trickflow heads on it but am waiting on a coupon or Ebay sale.
