P.S. Early Nova blocks had a recessed oil filter to clear the power-assist. You could use a non-Nova block, with a shorter spin-on oil filter. But blocks with the old cannister filter can't be used...unless you use an adapter to convert to spin-on filters.
My information shows the Chevy II blocks had a recessed filter to clear the clutch linkage cross shaft,... to use a non-Chevy II block with a mechanical clutch linkage several of the Nova resto suppliers sell a special aftermarket clutch pivot ball bracket to bolt to a non-Chevy II block.
Maybe it is a combo of both power steering slave clearance and clutch linkage clearance that the filter pad is recessed?? Anybody out there know for sure??
