About a 1/4 inch mabye more, I told him to machine it as low as he could and still have a flange that is strong enough to bolt down. I am lowering the motor, 1 1/2 and should clear NO PROBLEM. Like I said, This is the intake I will be selling after completion of my sheetmetal intake. I am going to measure all of the changes I make to the height of the motor mounts, so the Pathy questons will be answered. I am relocating the turbo, so... Clearance problems have been solved for this intake.
