I have a project i want to get going. I want to install a 5.4 dohc Navigator engine (99 Cobra cams) in a 72 ranchero. I picked up a m112 blower and want to run it on the 5.4 non-intercooled. With the extra cubes and lower rpms hopefully the boost won't be over 6psi but we'll see. I am running adapter plates by the way.
