M-1 Intake Manifold
Since this thread came up, and I haven't installed the engine yet, I will show what I did. I opened the top slightly, and radius the opening. I drilled and tapped for a coolant sensor or nipple for a heater hose. There is a boss in the coolant passage, I drilled through it and installed pipe plugs for now. It will be getting a nitrous plate and a 2" spacer.
