As far as I know, the 351 C Boss engine has the dipstick calibrated for 6

quarts of oil with the same oil pan as the 4V. The only difference that I

can imagine that can make a difference regarding oil consumption is that

the 4V has a rope type rear oil seal, and the Boss has the rubber type, but

I really don't think that this difference has any importance. Anyway, I

have now installed the rubber type seal in my engine when I rebuilt it. I

have always used 6 quarts (or, to be more accurate, 6 litres, but there is

not so much difference) in my engine, and I have calibrated my dipstick so

that I can see exactly how many litres of oil there is in the sump.

This is especially true if you are using a high volume pump, which is why

many engine builders do not recommend using them on Clevelands unless they

have the had the oiling galleys modified to reduce the oil flow to the

lifters, and hence up the pushrod tubes into the valve covers.

stuck up in the valve covers.  If you are worried about the extra quart

being "too much", I would be substantially more worried about the "too

little" condition.  With "too much" oil you might burn a little more oil,

with "too little" you might break something expensive  8<) ...
