Here is the first start of our latest 390 build with the intake and carbs crossram added. It idles amazingly well for a rough tune on the new Holley 390 CFM carbs and a pretty good size roller cam on this fresh build with less than 45 minutes on it. The crossram does not have any provisions for a PCV valve so it will take putting some miles on the engine to seat the rings in order to get rid of the minor blow by smoke coming out of the filler tube cap. We take the cars out after the engine is installed and give them a half dozen or so romps of full throttle acceleration followed by deceleration in the top gear to help seat the rings.
