If the oil level is carefully monitored, it should be fine.

When you run at the minimum mark, at max intermittant revs (6350 for the Pinto) as specified by Ford there is only 0.75 litre left in the sump pan which is about 20mm. The pick up pipe is 6mm from the sump pan floor!
At 7300 revs the pick up starts to draw air - I found out the hard way
It's made worse because at high revs and higher blow-by the oil can't drain back from the head properly.
The margin of error is the difference between min and max.
