Hi All, I'm close to completing a full overhaul of the 400, and want to get it on a dynamometer for breakin testing, and leak search before setting it back in. The local dyno is concerned about his exhaust ducts not being able to marry up to my manifolds. He hasn't seen the engine yet of course, but thought I'd ask you guys if anyone has dyno tested with long branch manifolds before? Any helpful tips?
