If you let the bellhousing stick out by about 25 mm, (as per book; i.e. crankshaft 130 mm above base of chassis) you'll have plenty of road clearance, and the valve cover will fit under the bonnet nicely (Saturn nose and scuttle). My only problem is that I used the original intake manifold, and had just 80 mm clearance above the throttle body, when the mounting flange diameter is 70 mm. I found an air hose forom a 1997 Escort to connect MAF to the throttle body.
In the end I've cut this pipe and stretched it to fit with a heat gun and a lot of persuasion. It's not ideal airflow-wise.
