If difference of opinion makes horse races you guys should be lining up in the gates! I've been runnig copper lines on my pick-up for over 30 years. No leaks! He said he was ready to "fire" it . If he's wrong maybe the water leaks will put out the flames! This is a great looking engine/car and looks to be well done. I'm sure enough has been made of this that ratatat will keep a close eye on it . Rat thanks for keeping the 216, they are great engines. Whth that low milage I bet yours still has shims left! Take short cuts and you'll never see these guys. It makes me smile!!!
